Severity: critical
Tags: security
Justification: breaks the whole system
kernel oops while trying to do a snmpwalk from a remote host. the entire
udp stack becomes unresponsive and reboot fails when trying to bring
down network interfaces. unsure if this is exploitable for a DoS attack,
will investigate further when i have time if this not a know issue.

[ Dann Frazier ]
* mckinley_icache.dpatch:
[Security] Fix a cache coherency bug unearthed by a new ia64 processor,
codenamed Montecito. This bug causes data corruption that has manifested
itself in kernel hangs and userspace crashes, and causes d-i to fail.
Reference: http://www.intel.com/cd/ids/developer/asmo-na/eng/215766.htm
N.B: I have marked this as security as it seems that it would
be trivial to construct a user-space DoS - Simon Horman.

[ Simon Horman ]
# Excluded from security-only release
# * drivers-net-via-rhine-wol-oops.dpatch (removed):
# This patch breaks the via-rhine driver and 2.6.8 and is
# completely bogus for this version of the kernel
# (closes: #311357)
.
* arch-x86_64-kernel-ptrace-boundary-check.dpatch
[Security, x86_64] Don't allow accesses below register frame in ptrace
See CAN-2005-1763.
.
* arch-x86_64-kernel-ptrace-canonical-rip-1.dpatch
[Security, x86_64] This works around an AMD Erratum by
checking if the ptrace RIP is canonical.
See CAN-2005-1762
.
* arch-x86_64-kernel-ptrace-canonical-rip-2.dpatch
[Security, x86_64] Fix canonical checking for segment registers in ptrace
See CAN-2005-0756
.
* arch-x86_64-kernel-smp-boot-race.dpatch
[Security, x86_64] Keep interrupts disabled during smp bootup
This avoids a race that breaks SMP bootup on some machines.
.
* arch-x86_64-mm-ioremap-page-lookup.dpatch
[Security, x86_64] Don't look up struct page pointer of physical address
in iounmap as it may be in a memory hole not mapped in mem_map and that
causes the hash lookup to go off to nirvana.
.
# Excluded from security-only release
# * drivers-media-vidio-bttv-vc100xp-detect.dpatch
# Allow Leadtek WinFast VC100 XP cards to work.
.
* fs-exec-ptrace-core-exec-race.dpatch
[Security] Fix race between core dumping and exec with shared mm
.
* fs-exec-ptrace-deadlock.dpatch
[Security] Fix coredump_wait deadlock with ptracer & tracee on shared mm
.
* fs-exec-posix-timers-leak-1.dpatch,
[Security] fs-exec-posix-timers-leak-2.dpatch
Make exec clean up posix timers.
.
* fs-hfs-oops-and-leak.dpatch
[Security] Fix a leak in HFS and HFS+
Fix an oops that occurs when an attempt is made to
mount a non-hfs filesystem as HFS+.
N.B: Marked as security as users may have mount privelages.
.
# Excluded from security-only release
# * fs-jbd-checkpoint-assertion.dpatch
# Fix possible false assertion failure in log_do_checkpoint(). We might
fail
# to detect that we actually made a progress when cleaning up the
checkpoint
# lists if we don't retry after writing something to disk.
.
* mm-mmap-range-test.dpatch
[Security] Make sure get_unmapped_area sanity tests are done regardless of
wheater MAP_FIXED is set or not.
See CAN-2005-1265
.
# Excluded from security-only release
# * mm-rmap-out-of-bounds-pte.dpatch
# Stop try_to_unmap_cluster() passing out-of-bounds pte to pte_unmap()
.
* net-bridge-netfilter-etables-smp-race.dpatch
[Security] The patch below fixes an smp race that happens on such
systems under heavy load.
.
Excluded from security-only release
* net-bridge-mangle-oops-1.dpatch, net-bridge-mangle-oops-2.dpatch
Fix oops when mangling and brouting and tcpdumping packets
Needed for net-bridge-forwarding-poison-1.dpatch
.
* net-bridge-forwarding-poison-2.dpatch,
net-bridge-forwarding-poison-2.dpatch:
[Security] Avoid poisoning of the bridge forwarding table by frames that
have been dropped by filtering. This prevents spoofed source addresses on
hostile side of bridge from causing packet leakage, a small but possible
security risk.
.
# Excluded from security-only release
# * net-ipv4-netfilter-ip_queue-deadlock.dpatch
# Fix deadlock with ip_queue and tcp local input path.
.
* [Security] net-rose-ndigis-verify.dpatch
Verify ndigis argument of a new route.
.
* sound-usb-usbaudio-unplug-oops.dpatch
[Security] Prevent oops & dead keyboard on usb unplugging while the device
is being used.
.
* net-ipv4-ipvs-conn_tab-race.dpatch
[Security] Fix race condition on ip_vs_conn_tab list modification
.
# Excluded from security-only release
# * asm-i386-mem-clobber.dpatch:
# Make sure gcc doesn't reorder memory accesses in strncmp and friends on
# i386.
.
# Excluded from security-only release
# * drivers-acpi-pci_irq-elcr.dpatch:
# Make sure we call acpi_register_gsi() even for default PCI interrupt
# assignment. That's the part that keeps track of the ELCR register, and we
# want to make sure that the PCI interrupts are properly marked level/low.
.
* asm-i386-mem-clobber.dpatch:
Make sure netlink_autobind() propagates the error return from
netlink_insert(). Otherwise, callers will not see the error as they
should and thus try to operate on a socket with a zero pid, which is very
bad.
.
* fs-ext3-64bit-offset.dpatch
[Security] Incorrect offset checks for ext3 xattr on 64 bit architectures
an lead to a local DoS.
See CAN-2005-0757. (see: #311164).
.
* arch-x86_64-mm-mmap.dpatch
[Security, x86_64] Compat mode program can hang kernel
See CAN-2005-1765.
.
* arch-ia64-ptrace-getregs-putregs.dpatch
[Security, ia64] Fix unchecked user-memory accesses in ptrage_getregs()
and ptrace_setregs.
.
* arch-ia64-ptrace-restore_sigcontext.dpatch
[Security, ia64] Fix to prevent users from using ptrace to set the pl field
of the ar.rsc reginster to any value, leading to the
ability to overwrite kernel memory.
Note, this patch requires the arch-ia64-ptrace-getregs-putregs.dpatch
patch to apply cleanly.
See CAN-2005-1761.
.
# Excluded from security-only release
# * Makefile-gcc-3.3.dpatch, control
# Build with gcc-3.3, as gcc-4.0, now the dedault in unstable,
# fails to build this source. As this tree is primarily
# intended for use with sarge, there seems little point
# in putting in gcc-4.0 fixes, but at the same time,
# there is some value in being able to use it with unstable.
