Ubuntu priority
The l2tp_ip6_getname function in net/l2tp/l2tp_ip6.c in the Linux kernel before 3.6 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel stack memory via a crafted application.
From the Ubuntu Security Team
Mathias Krause discovered an information leak in the Linux kernel's implementation of getsockname for Layer Two Tunneling Protocol (L2TP). A local user could exploit this flaw to examine some of the kernel's stack memory.
