Description
This security bulletin contains information about 1 security vulnerability.
1) Input validation error (CVE-ID: CVE-2014-2309)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The ip6_route_add function in net/ipv6/route.c in the Linux kernel through 3.13.6 does not properly count the addition of routes, which allows remote attackers to cause a denial of service (memory consumption) via a flood of ICMPv6 Router Advertisement packets.
Remediation
Install update from vendor's website.
