CVE-2014-9730
Published: 31 December 2014
The udf_pc_to_char function in fs/udf/symlink.c in the Linux kernel before 3.18.2 relies on component lengths that are unused, 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 correctly verify the component length for symlinks. 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.
