CVE-2011-1093
Publication date 18 July 2011
Last updated 24 July 2024
Ubuntu priority
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.
From the Ubuntu Security Team
Johan Hovold discovered that the DCCP network stack did not correctly handle certain packet combinations. A remote attacker could send specially crafted network traffic that would crash the system, leading to a denial of service.
