2010-06-01 Thread Kees Cook
Ah-ha, I see the problem now.  This vulnerability was introduced after
all the versions of net-snmp that were in the archive at the time the
CVE was published.  At some point Debian packaged the 5.4.x series from
a point that did not include the fix, which is why only Lucid and later
have the problem.

[Bug 719833] [NEW] ssh upstart job fails to actually bring up ssh

2011-02-15 Thread Kees Cook
Public bug reported:

When I reboot my router, ssh does not start.

Feb 15 22:51:32 router init: ssh main process (897) terminated with status 255
Feb 15 22:51:32 router init: ssh main process ended, respawning
Feb 15 22:51:32 router init: ssh main process (915) terminated with status 255
Feb 15 22:51:32 router init: ssh respawning too fast, stopped

I do not bind to 0.0.0.0, so I must have networking up fully before ssh
can start.  Because "filesystem" happens before "networking" has
started, the job fails. We might want to consider changing the upstart
job to:

start on filesystem and started networking

[Bug 722386] Re: sshd buffer overflow detected crash from certain ip addresses

2011-02-21 Thread Kees Cook
The backtrace shows that this is from the pgsql PAM module. A quick
check of the code shows that it is assuming that h_addr is always an
IPv4 when it may not be, resulting in a potential overflow of the buffer
it creates to hold an IP address.

[Bug 722815] Re: apparmor prevents ntp from reading gpsd

2011-03-10 Thread Kees Cook
Thanks for tracking this down! Unfortunately, ipc_owner is a rather
strong capability (allows access to all shared memory), and it looks
like ntpd expects to actually write to the memory region (e.g.
"shm->valid = 0" is in the code), so SHM_RDONLY doesn't seem viable
either. Instead, I've added a note to the AppArmor profile itself
pointing people to the right option if they want to enable it for their
local system (since it doesn't seem appropriate to do this by default
for all ntpd users).

[Bug 768707] [NEW] cyrus-sasl2-heimdal uninstallable and ftbfs

2011-04-21 Thread Kees Cook
Public bug reported:

cyrus-sasl2-heimdal 2.1.23.dfsg1-5.1ubuntu1 is uninstallable with cyrus-
sasl2 2.1.23.dfsg1-5ubuntu3, and ftbfs due to heimdal changes, from what
I can see. I suspect the only way forward on this is to get cyrus-sasl2
2.1.23.dfsg1-6 (or, likely, newer) into natty which merges in the
heimdal source and fixes the compilation problems.

Just as a note, due to Ubuntu's default compiler flags[1], this
vulnerability is "only" a denial-of-service and does not seem to result
in arbitrary code execution.

AAaargh. Who reimplements sprintf!? I am working on hardy and dapper
now. Will have this uploaded shortly. Thanks for double-checking and
getting the Lucid and Oneiric patches ready!

At least full ASLR (PIE[1]) is in place in Lucid and later, so
exploiting this is difficult, but not impossible.

[Bug 1534340] [NEW] openssh server 6.6 does not report max auth failures

2016-01-14 Thread Kees Cook
Public bug reported:

Brute force attacks against openssh on Trusty will not log "max auth"
key-based attempts, leaving their brute forcing invisible to the logs
and anything that consumes logs, like fail2ban. Version 6.7 introduced
the logging, but it's missing in Trusty. Since Trusty is LTS, it would
seem sensible to have this feature backported.

[Impact] Bruce force attempts using private keys are invisible to logs,
which renders defenses like fail2ban useless.

[Test case] Create 20 SSH keys, try to log in over SSH, note lack of
logging the failures.

[Regression Potential] Very unlikely regression potential as the "max
auth" condition is already handled in code, it just wasn't logging. The
change only adds the missing logging.

Seems to break slaved domain updates. (i.e. my server is secondary for a

into the kernel logs.)

Since the /var/cache line has "l" already, it seems like just a simple
fix; I didn't investigate the true origin.

[Bug 655442] [NEW] memory content leak when using invalid utf-8 with XMLWriter::writeAttribute

2010-10-05 Thread Kees Cook
*** This bug is a security vulnerability ***

Public security bug reported:

Binary package hint: php5

It seems that PHP is not correctly using libxml2's xmlwriter routines,
and allows passing in invalid utf-8 strings which are then misparsed by
libxml2, allowing memory contents to leak into the resulting output.

Actual output:
PHP Warning:  XMLWriter::writeAttribute(): string is not in UTF-8 in 
/tmp/xmlwriter.php on line 12


Expected output:

[Bug 671672] [NEW] Sync krb5 1.8.3+dfsg-2 (main) from Debian unstable (main)

2010-11-05 Thread Kees Cook
Public bug reported:

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA512

 affects ubuntu/krb5
 status confirmed
 importance wishlist
 subscribe ubuntu-archive
 done

Please sync krb5 1.8.3+dfsg-2 (main) from Debian unstable (main)

Explanation of the Ubuntu delta and why it can be dropped:
Ubuntu changes are in Debian too now (MITKRB5-SA-2010-006)

Changelog entries since current natty version 1.8.1+dfsg-5ubuntu0.1:

krb5 (1.8.3+dfsg-2) unstable; urgency=high

  * MITKRB5-SA-2010-006 [CVE-2010-1322]: null pointer dereference in
kdc_authdata.c leading to KDC crash, Closes: #599237
  * Fix two memory leaks in krb5_get_init_creds path; one of these memory
leaks is quite common for any application such as PAM or kinit that
gets initial credentials, thanks Bastian Blank, Closes: #598032
  * Install doc/CHANGES only in krb5-doc, not in all packages, saves
several megabytes on most Debian systems, Closes: #599562

 -- Sam Hartman   Wed, 13 Oct 2010 10:41:19 -0400

krb5 (1.8.3+dfsg-1) unstable; urgency=low

  * New Upstream release; only change is version bump from beta1 to final 
  * Bring back a libkrb53 oldlibs package. Note that this is technically a
policy violation because it doesn't provide libdes425.so.3 or
libkrb4.so.2 and thus provides a different ABI. However, some
packages, such as postgres8.4 require the lenny version to be present
for the squeeze transition, so we cannot force the removal of
libkrb53's reverse dependencies. We can conflict or break with lenny
packages that will not work with this libkrb53, but we may break
out-of-archive packages without notice. Absent someone coming up with
a patch to the modern libk5crypto-3 that allows it to work with the
lenny libkrb53 (a weekend's worth of work proved this would be quite
difficult), this is the best solution we've come up with, Closes: #596678

 -- Sam Hartman   Sun, 19 Sep 2010 14:59:46 -0400

krb5 (1.8.3+dfsg~beta1-2) unstable; urgency=low

  * Remove documentation that has moved to the krb5-appl package and is
not shipped upstream from Debian diff

 -- Sam Hartman   Tue, 10 Aug 2010 15:33:15 -0400

krb5 (1.8.3+dfsg~beta1-1) unstable; urgency=low

  * New Upstream version
  * Add breaks with libkrb53 because libdes425 cannot work with new
libk5crypto3 (Closes: #557929)
  * You want this version: it fixes an incompatibility with how PACs are
verified with Windows 2008
  * As a result of libkrb53 breaks, we no longer get into problems with
krb5int_hmac, Closes: #566988 
  * Note that libkdb5-4 breaks rather than conflicts libkadm5srv6, Closes:
#565429
  * Start kdc  before x display managers, Closes: #588536

[Bug 684874] Re: Merge rabbitmq-server 2.2.0-1 (main) from Debian unstable (main)

2010-12-06 Thread Kees Cook
Based on the comments in bug #506985, I think this delta should have
been dropped in maverick (it was only to support pre-lucid upgrades).
After looking at the package diffs, this is the only real difference
between Ubuntu and Debian now, so I think this bug should be changed
from a merge to a sync.

** Summary changed:

- Merge rabbitmq-server 2.2.0-1 (main) from Debian unstable (main)

[Bug 691414] [NEW] clamav taking extremely long time to load database

2010-12-16 Thread Kees Cook
Public bug reported:

Binary package hint: clamav

# apt-cache policy clamav-daemon
clamav-daemon:
  Installed: 0.96.3+dfsg-2ubuntu1.0.10.04.2
  Candidate: 0.96.3+dfsg-2ubuntu1.0.10.04.2

Since the security update of clamav, the daemon takes multiple minutes
to load its virus database, and is causing random timeouts for users of
the unix socket (in my case, mimedefang), triggering repeated 400-series
email temp-fails each time freshclam issues a reload request.

strace just shows it slowly allocating memory and not doing much else.

Logs don't seem to help:

But minutes later, it's still spinning at 100% CPU and non-responsive on
its socket.

DEP-3 and fix up the formatting of the changelogs a bit ("CVE-" vs "CVE:
"), and get these building.

[Bug 801501] Re: [MIR] nova

2011-09-12 Thread Kees Cook
Quick notes:
 * should use /run instead of /var/run
 * while it's nice to have the sudoers split, the sudoers fragment is wildly 
permissive ("chown" as root is trivial to exploit). I would recommend specific 
helper scripts that validate the logic of the requested dangerous commands (see 
the similar stuff in euca).

This is a rather large chunk of python daemons. I think a much more
complete security audit should be done, but that's not something I have
time for at the moment. On the up side, the code looks generally well
designed, though not really made to resist malicious admin use. Given
the scope of its intended use, I think it would be wise to keep this out
of main until it can really be more heavily audited. Trying to map the
dispatch actions to the possible code paths would probably take some
effort, and I'm worried that some of the web objects might have
unexpected exposed functions. Though perhaps I'm just not familiar
enough with the WSGI code.

[Bug 801501] Re: [MIR] nova

2011-09-13 Thread Kees Cook
This is a step in the right direction (regex arg filtering is better
than filename-glob filtering), but I think this probably needs to have
even more logic built in. For example, running "ip ... $interface ..."
might need logic to have the wrapper look up the interface and decide if
it is actually a nova-controlled interface, etc. Overall, the trajectory
for this design looks fine -- there is a well-defined boundary between
"nova" and "root". Continuing to get it even more highly specified is
the right way to go.

[Bug 556167] Re: vmbuilder uses parted to create disk images, which leads to broken sector counts (cannot use grub2 on disk images created by vmbuilder/parted)

2011-11-07 Thread Kees Cook
The problem is that parted treats local files (as used by vmbuilder)
differently from "actual" disk files, and changes the sector size
accordingly (without an option to change it). As a result, the partition
start locations are too small for grub2 to install. I had originally
reproduced this by using vmbuilder to install Ubuntu, and then
attempting to update to grub2, which would fail, since there wasn't
enough room.

My previously attached hack/work-around for vmbuilder was to skip a
sector when building the first partition.

2011-11-16 Thread Kees Cook
Hm, I don't agree. I think the problem is in libparted/arch/linux.c
init_file():

dev->bios_geom.sectors = 32;

vs _device_probe_geometry() which defaults to what the LBA reports or:

dev->bios_geom.sectors = 63;

So, when vmbuilder uses parted to build the disk, parted treats the disk
file differently than it would a real LBA mode drive. Fixing this is the
core cause of the problem, as far as I see it.

Right, I don't meant to ditch the fingerprint report, but instead, allow
one to skip the ssh-keyscan step, and just pull the .pub file directly out
of the console output. i.e. _add_ it to the console output.

[Bug 510732] Re: OpenSSH server sshd_config PermitRootLogin -> NO

2010-01-21 Thread Kees Cook
The issue is a trade-off between three classes of people, I think:
 - People that have systems where root can SSH in (which consists of):
  - Those that want to SSH in as root
  - Those that are surprised they can SSH in as root
  - Those that don't care

http://cheezburger.com/View.aspx?aid=3094191616

By changing the default to "no", we protect the class of people that
don't care, and irritate the people that expect to log in as root.  By
leaving the default as "yes", the class of people that don't care are
vulnerable, but irritate the people that think this is insecure.

The choice depends on the perceived benefit in protecting that class of
user while weighed against those expecting to log in as root without
having to also change SSH configs.  Is the dark green area larger than
the blue area?

[Bug 510732] Re: OpenSSH server sshd_config PermitRootLogin -> NO

2010-01-21 Thread Kees Cook
"authoritative resources"?  I'm inferring that you think my use of a
simple diagram tool to help illustrate this bug is somehow
inappropriate?  And yes, I know what layered security is.  :)

Please understand that the PermitRootLogin config default is not a new
issue.  I'm trying to make sure everyone can have the same language to
discuss it, as this has traditionally been what has derailed discussions
before.  Also, I did not mention in my first comment, but I support
changing this setting.  That said, Ubuntu tries to make its decisions
via consensus, which this issue does not have.  I'm hoping to build such
a consensus.

The primary concern I have is for the safety of Ubuntu users, though it
must be balanced against usability.  A default system doesn't even have
openssh-server installed (it is, of course, installed on nearly all
server systems).  A system _with_ openssh-server does not allow root
login because the root user's password is locked.  Therefore, the bulk
of Ubuntu users are protected already from root-targeted SSH brute-force
attacks.

This bug is explicitly about the behavior of an already non-default
system (openssh-server installed, root password enabled).  For this
minority of Ubuntu systems, the PermitRootLogin setting currently
creates a problem for the people that aren't thinking about how brute
forcing might compromise them (i.e. people that did not understand the
implications of enabling the strongly discouraged root password).
Changing the setting protects these people and gets in the way of people
that do not know how to change PermitRootLogin to "yes".

This is sensible.  If too much detection stuff like this ends up in
update-notifier, I suspect we can just create a new package called "cpu-
checker", which is the bzr tree I've current got the check-bios-nx code
and test suite in.

On another note, I would like to see kvm-ok improved somehow so that it
is accurate after a system has been running for a while.  Right now, if
a system has been running a while and dmesg has scrolled off the top, or
if the "kvm" module hasn't yet loaded, there's no feedback on if VT is
disabled in the BIOS.

[Bug 103010] Re: qemu no tun/tap networking

2010-03-08 Thread Kees Cook
Please see https://help.ubuntu.com/community/KVM/Networking for a
discussion of the issue.  (Basically, it is unsafe to ship it this way
as it gives any local user the ability to disrupt networking.)

[Bug 103010] Re: qemu no tun/tap networking

2010-03-09 Thread Kees Cook
@Chris Yup, I understand how capabilities work.  I'm actively working on
getting fscaps functioning with Debian/Ubuntu packaging (see
https://wiki.ubuntu.com/Security/FilesystemCapabilties).  (You seemed to
miss me changing "ep" to "ei" in the wiki -- I've added the old
instructions back and clarified the procedure.)

Just because qemu claims to only work on tun/tap devices doesn't mean it
can't be subverted into working on arbitrary network devices.  In a
perfect world, upstream qemu will create a helper tool that is uses
fscaps, etc, and correctly manages the tun/tap devices before launching
qemu itself.  That reduces the exposure of CAP_NET_ADMIN and makes for a
more auditable chunk of code.

I'll leave it up to the qemu maintainer in Ubuntu how to handle these
things, but I just wanted to confirm that arbitrarily giving everyone
CAP_NET_ADMIN (or being setuid root) via qemu was not preferred.  If
it's done via file permissions and a qemu-runners group, plus fscaps
=ep, or done via fscaps =ei and select users are given =i via pam_cap, I
don't much care.  :)

Regardless, fscaps are not supported in Debian/Ubuntu packaging (which I
very much want to fix), so this is all a non-issue until that is solved.
In the meantime, I feel it is my responsibility to provide as safe a set
of instructions that accomplishes the goal of accessing the tun/tap
devices.

[Bug 540596] [NEW] NX memory not simulated for ARMv7 and above CPUs

2010-03-17 Thread Kees Cook
Public bug reported:

Binary package hint: qemu-kvm

The ARM emulation in qemu does not appear to correctly simulate non-
executable memory for the CPUs that support it (ARMv7, maybe v6, and
above).

[Bug 556167] [NEW] vmbuilder uses parted to create disk images, which leads to broken sector counts (cannot use grub2 on disk images created by vmbuilder/parted)

2010-04-05 Thread Kees Cook
Public bug reported:

parted uses a fixed sector count of "32" when writing partitions to a
non-block device.  (See init_file() via linux_new() in
libparted/arch/linux.c)  As a result, the track size of disks created
with vmbuilder is 32 sectors, not the generally expected 63 sectors
(used with LBA mode).  This means that the "embedding region" between
the end of the MBR and the start of partition 1 is half the "normal"
size, and grub2 will not install.

/usr/sbin/grub-setup: warn: Your embedding area is unusually small.
core.img won't fit in it..

Fastest solution I see is to use an environment override as already done
in init_file() for sector size.  Perhaps PARTED_SECTORS?  And then set
this to 63 when calling parted from vm-builder.
