Detailsinfo

A vulnerability was found in Linux Kernel 3.10/3.12/3.13 (Operating System). It has been declared as problematic. This vulnerability affects the function ip6_route_add of the file net/ipv6/route.c of the component Router Advertisement Handler. The manipulation with an unknown input leads to a numeric error vulnerability (Remote). The CWE definition for the vulnerability is CWE-189. As an impact it is known to affect availability. CVE summarizes:

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.

The weakness was presented 03/06/2014 by Sabrina Dubroca as ipv6: don't set DST_NOCOUNT for remotely added routes as confirmed git commit (GIT Repository). The advisory is available at git.kernel.org. The public release was coordinated in cooperation with the vendor. This vulnerability was named CVE-2014-2309 since 03/06/2014. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 73241 (Fedora 20 : kernel-3.13.7-200.fc20 (2014-4317)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Fedora Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 167699 (SUSE Enterprise Linux Security update for Linux kernel (SUSE-SU-2015:0481-1) - (Deprecated)).

Applying a patch is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 16443.
