CVE-2013-0310

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.4.8

Description The issue allows local users to cause a denial of service, resulting in a system crash due to a NULL pointer dereference. This is achieved through an IPOPT CIPSO IP OPTIONS setsockopt system call. The cipso v4 validate function in net/ipv4/cipso ipv4.c is the vulnerable component.

Recommendations For Linux kernel versions prior to 3.4.8, update to version 3.4.8 or later to resolve the issue. As a temporary workaround, consider restricting access to the setsockopt system call to minimize the risk of exploitation.
