Ubuntu Security Notice USN-1245-1

Posted Oct 25, 2011

Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1245-1 - Ryan Sweat discovered that the kernel incorrectly handled certain VLAN packets. On some systems, a remote attacker could send specially crafted traffic to crash the system, leading to a denial of service. Vasiliy Kulikov and Dan Rosenberg discovered that ecryptfs did not correctly check the origin of mount points. A local attacker could exploit this to trick the system into unmounting arbitrary mount points, leading to a denial of service. Various other issues were also addressed.
