Description Jean-François Brunette (RETIRED) gentoo-dev 2005-08-05 06:30:56 UTC 
Not considered as critical, but I just do my job and report it ;)

------------------------------------------
Description:
Balazs Scheidler has reported a vulnerability in the Linux kernel, which
potentially can be exploited by malicious, local users to cause a DoS (Denial of
Service).

The vulnerability is caused due to a boundary error in the XFRM code and can be
exploited to cause an array indexing overflow.

Solution:
The vulnerability has been fixed in versions 2.6.13-rc4 and later.

Updating URL to point at the patch which was applied to Linus' tree.

This was fixed in gentoo-sources-2.6.12-r7 (genpatches-2.6.12-11)
