Detailsinfo

A vulnerability classified as critical has been found in Linux Kernel 2.6.16.59 (Operating System). Affected is the function ip6_dst_lookup_tail. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. CVE summarizes:

The ip6_dst_lookup_tail function in net/ipv6/ip6_output.c in the Linux kernel before 2.6.27 does not properly handle certain circumstances involving an IPv6 TUN network interface and a large number of neighbors, which allows attackers to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via unknown vectors.

The issue has been introduced in 03/20/2006. The weakness was released 03/24/2010 as Bug 563781 as not defined bug report (Bugzilla). The advisory is available at bugzilla.redhat.com. This vulnerability is traded as CVE-2010-0437. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details and a public exploit are known.

The exploit is shared for download at exploit-db.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1465 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 45092 (CentOS 5 : kernel (CESA-2010:0147)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 118967 (VMware ESX Security Update for Third-Party Components (VMSA-2011-0003)).
