Secunia: A vulnerability has been reported in Linux Audit, which potentially can be exploited by malicious, local users to gain escalated privileges. The vulnerability is caused due to a boundary error within the "audit_log_user_command()" function in lib/audit_logging.c. This can be exploited to cause a stack-based buffer overflow via an overly long "command" argument and potentially execute arbitrary code with the privileges of the application using libaudit. The vulnerability is reported in versions prior to 1.7. Original Advisory: http://people.redhat.com/sgrubb/audit/ChangeLog
ebuild in the tree. the stock audit.rules probably need some work on Gentoo, the last item remaining from bug 184563.
(In reply to comment #1) > ebuild in the tree. the stock audit.rules probably need some work on Gentoo, > the last item remaining from bug 184563. Do you want to fix that before we do a security stabling, or should we just go ahead now?
arches, sorry for spam
FYI: https://bugzilla.redhat.com/show_bug.cgi?id=438840 http://cvs.fedoraproject.org/viewcvs/rpms/audit/devel/audit-1.7.1-overflow.patch?rev=1.1&view=markup
Any news here? Can we go ahead and CC arches for stabling 1.7?
Please bump to 1.7.1 (or 1.7.3) 1.7.1 - Remove LSB headers info for init scripts - Fix buffer overflow in audit_log_user_command, again (#438840)
1.7.3 in the tree now. I knew 1.7 had some troubles. We do need to update the Gentoo-bundled rules however, but I think that shouldn't hold back stabling - anybody making serious use of audit would have their own rulesets.
Arches, please test and mark stable: =sys-process/audit-1.7.3 Target keywords : "amd64 hppa ia64 ppc release sparc x86"

opfer: look at the path of the python compile error - /usr/lib/python2.4/site-packages/BicycleRepairMan_Idle.py. That's COMPLETELY unrelated to sys-process/audit.
Stable for HPPA.
x86 stable, @robbat2: Ooops
amd64 stable
ia64/sparc stable
ppc stable
Ready for vote, I vote YES.
Fixed in release snapshot.
voting YES too, GLSA draft filed.
