Description

This security bulletin contains information about 1 security vulnerability.


1) NULL pointer dereference (CVE-ID: CVE-2013-6431)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in net/ipv6/ip6_fib.c in the Linux kernel before 3.11.5 does not properly implement error-code encoding, which allows local users to cause a denial of service (NULL pointer dereference and system crash) by leveraging the CAP_NET_ADMIN capability for an IPv6 SIOCADDRT ioctl call. A remote attacker can perform a denial of service (DoS) attack.
