Candidate: CVE-2006-5755
References:
http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=658fdbef66e5e9be79b457edc2cbbb3add840aa9
Description:
Linux kernel before 2.6.18, when running on x86_64 systems, does not
properly save or restore EFLAGS during a context switch, which allows
local users to cause a denial of service (crash) by causing SYSENTER
to set an NT flag, which can trigger a crash on the IRET of the next
task.
Ubuntu-Description:
The task switching code did not save and restore EFLAGS of processes.
By starting a specially crafted executable, a local attacker could
exploit this to eventually crash many other running processes. This
only affects the amd64 platform.
Notes:

dannf> marking sarge/2.4 N/A since we released no sarge/2.4/amd64 kernel
dannf> ignoring for sarge7 because backport is non-trivial
jmm> Affects xen
