CVE-2013-4247

Published: 14 August 2013

Off-by-one error in the build_unc_path_to_root function in fs/cifs/connect.c in the Linux kernel before 3.9.6 allows remote attackers to cause a denial of service (memory corruption and system crash) via a DFS share mount operation that triggers use of an unexpected DFS referral name length.

From the Ubuntu security team

Marcus Moeller and Ken Fallon discovered that the CIFS incorrectly built certain paths. A local attacker with access to a CIFS partition could exploit this to crash the system, leading to a denial of service.
