I don't know whether potato, woody, sarge and sid should have a security bug filed against them.
According to http://packages.qa.debian.org/m/mgetty.html sid has version 1.1.30-1, sarge has version 1.1.28-5, and woody has version 1.1.27-4.1. Note that Debian packages contain changes. I have not looked to see if these changes might fix the issues, but they should be visible in the http://saens.debian.org/debian/pool/main/m/mgetty/ directory as the *.diff.gz files. Note that it looks like potato contains mgetty 1.1.21-3potato1 which is a version of mgetty that contains a security fix that fixes the "Immunix reports that mgetty does not create temporary files in a secure manner, which could lead to a symlink attack." bug. I'd imagine this change would have been incorporated in later versions. The changelog for version 1.1.23-3 says: mgetty (1.1.21-3) stable; urgency=low * make mgetty-fax's postinst create /var/spool/fax/outgoing/.last_run to close a potential symlink exploit by members of the fax group that is otherwise possible until that file is created -- Philip Hands <[EMAIL PROTECTED]> Thu, 31 Aug 2000 19:05:13 +0100 I can't see a changelog for version 1.1.23-3potato1, so maybe this is the diff file for that. http://search.alphanet.ch/cgi-bin/search.cgi?msgid=20021125142338.E12094%40greenie.muc.de&max_results=1&type=long&domain=ml-mgetty says: [...] Security fixes / concept changes: * it's now possible to run faxrunq/faxrunqd (and thus sendfax) as non-root user * fax spool directories are no longer world-writeable, access is done via a suid helper program (suid to a special user ID, "fax") * possible buffer overrun when calling cnd-program (if CallerName is too long) * $CALLER_ID, $CALLER_NAME and so on are sanitized before passing to shell (all quote characters and all non-printable characters are replaced by " ") [...] Who should upgrade? * everbody who is using faxspool/faxrunq on a machine that is shared with other users that are not 100 per cent trustworthy * vgetty users with V.253 modems Distribution vendors: - I strongly urge you to upgrade to 1.1.29 - older versions are NOT safe if there are malicious users on the system and faxrunq/faxrunqd are in use. - The fax queue handling (faxspool, faxq-helper) needs a new user ID now ("fax") which MUST own the fax queue directories and SHOULD NOT own anything else. The user ID is configured in the Makefile. - faxrunq/faxrunqd can run as user "fax", but in that case the user needs access to the modem devices (via his primary group id). Watch out for log file access permissions if this is used! If anything is unclear, *please* talk to me before rolling out updated packages that might break things in funny ways. [...] Please don't mail [EMAIL PROTECTED] until you are reasonably cetain potato or woody are vulnerable. Drew Daniels
