CVE-2011-4087

Published: 29 October 2011

The br_parse_ip_options function in net/bridge/br_netfilter.c in the Linux kernel before 2.6.39 does not properly initialize a certain data structure, which allows remote attackers to cause a denial of service by leveraging connectivity to a network interface that uses an Ethernet bridge device.

From the Ubuntu security team

Scot Doyle discovered that the bridge networking interface incorrectly handled certain network packets. A remote attacker could exploit this to crash the system, leading to a denial of service.
