CVE-2011-1093

[Andy Whitcroft]

The dccp_rcv_state_process function in net/dccp/input.c in the Datagram Congestion Control Protocol (DCCP) implementation in the Linux kernel before 2.6.38 does not properly handle packets for a CLOSED endpoint, which allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by sending a DCCP-Close packet followed by a DCCP-Reset packet.

Break-Fix: 7c657876b63cb1d8a2ec06f8fc6c37bb8412e66c 720dc34bbbe9493c7bd48b2243058b4e447a929d
