CVE-2012-0207

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.2.1

Description The issue allows remote attackers to cause a denial of service, resulting in a divide-by-zero error and a kernel panic, through IGMP packets. This is due to the igmp heard query function in net/ipv4/igmp.c.

Recommendations For Linux kernel versions prior to 3.2.1, update to version 3.2.1 or later to resolve the issue. As a temporary workaround, consider restricting access to IGMP packets to minimize the risk of exploitation.
