Description

This security bulletin contains information about 1 security vulnerability.


1) Buffer overflow (CVE-ID: CVE-2013-2237)

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

The key_notify_policy_flush function in net/key/af_key.c in the Linux kernel before 3.9 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel heap memory by reading a broadcast message from the notify_policy interface of an IPSec key_socket.
