Description Agostino Sarubbo gentoo-dev 2012-11-01 17:21:52 UTC
From https://secunia.com/advisories/49742/ :

Description
Two vulnerabilities have been reported in Linux Kernel, which can be exploited by malicious, local 
users to cause a DoS (Denial of Service).

1) An error when loading a sparing table can be exploited to cause a crash when mounting a 
specially crafted filesystem.

2) An error in the "udf_load_logicalvol()" function (fs/udf/super.c) when processing a partition 
table can be exploited to cause a crash when mounting a specially crafted filesystem.


Solution
Fixed in the GIT repository. Please note, Linux Kernel 3.3.x branch reached EoL (End of Life) in 
June 2012.

Comment 1 Aaron Bauman (RETIRED) gentoo-dev 2018-04-04 18:21:43 UTC
There are no longer any 2.x or <3.4.5 kernels available in the repository with the exception of sys-kernel/xbox-sources which is unsupported by security.
