+Description: 2.6.8 ia64 kernel w/ PREEMPT enabled permits local DoS (oops)
+Notes:
+ From: dann frazier <dannf@dannf.org>
+ To: team@security.debian.org
+ Subject: kernel-image-2.6.8-ia64 - disable preempt
+ Date: Fri, 25 Mar 2005 18:57:59 -0700
+ .
+ hey security team,
+ Its likely that kernel-image-2.6.8-ia64 (2.6.8-12) will be the version
+ that ships in sarge. This kernel has CONFIG_PREEMPT enabled, which has
+ at least one known issue in ptrace code that lets an unpriveleged
+ userspace process trigger an oops. This issue went away upstream by
+ 2.6.9, but its unclear what actually fixed it. SuSE/RedHat disable
+ PREEMPT for ia64 (or so I'm told), so they are not affected. This same
+ test case does _not_ fail on x86, which also has PREEMPT enabled for
+ sarge.
+ .
+ This issue has been known for a while, but I waited until after d-i
+ RC3 to upload it, since it changes the ABI. This fix is in the 2.6.8-13
+ build in unstable, but the release team is blocking this kernel from
+ normal sarge propagation to keep the kernel udebs in sync.
+ .
+ .
+ dannf> This is only a config change, so it requires no changes to
+ dannf> kernel-source-2.6.8, but I'll use the kernel-source version
+ dannf> for the pending/released tags to match the others.
