CVE-2009-2793
First published: Fri Sep 18 2009(Updated: )
The kernel in NetBSD, probably 5.0.1 and earlier, on x86 platforms does not properly handle a pre-commit failure of the iret instruction, which might allow local users to gain privileges via vectors related to a tempEIP pseudocode variable that is outside of the code-segment limits.
