CVE-2014-9728

Published: 31 December 2014

The UDF filesystem implementation in the Linux kernel before 3.18.2 does not validate certain lengths, which allows local users to cause a denial of service (buffer over-read and system crash) via a crafted filesystem image, related to fs/udf/inode.c and fs/udf/symlink.c.

From the Ubuntu security team

Carl H Lunde discovered that the UDF file system (CONFIG_UDF_FS) failed to verify symlink size info. A local attacker, who is able to mount a malicous UDF file system image, could exploit this flaw to cause a denial of service (system crash) or possibly cause other undesired behaviors.
