Description Robert Buchholz (RETIRED) gentoo-dev 2008-09-12 13:52:40 UTC 
CVE-2008-3911 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-3911):
  The proc_do_xprt function in net/sunrpc/sysctl.c in the Linux kernel
  2.6.26.3 does not check the length of a certain buffer obtained from
  userspace, which allows local users to overflow a stack-based buffer
  and have unspecified other impact via a crafted read system call for
  the /proc/sys/sunrpc/transports file.
Comment 1 kfm 2009-07-20 22:16:28 UTC 
Corrected Status Whiteboard (refer to relevant upstream ChangeLogs for corroboration). hardened-kernel unaffected at present time. Removing alias.

PS: genpatches-2.6.25-11 included 2.6.25.17. genpatches-2.6.26-3 included 2.6.26.4.
