CVE-2011-0709
Published: 18 February 2011
The br_mdb_ip_get function in net/bridge/br_multicast.c in the Linux kernel before 2.6.35-rc5 allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via an IGMP packet, related to lack of a multicast table.
From the Ubuntu Security Team
Frank Arnold discovered that the IGMP protocol did not correctly parse certain packets. A remote attacker could send specially crafted traffic to crash the system, leading to a denial of service.
