CVE-2014-9729

Published: 31 December 2014

The udf_read_inode function in fs/udf/inode.c in the Linux kernel before 3.18.2 does not ensure a certain data-structure size consistency, which allows local users to cause a denial of service (system crash) via a crafted UDF filesystem image.

From the Ubuntu Security Team

Carl H Lunde discovered that the UDF file system (CONFIG_UDF_FS) did not valid inode size information . 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.
