CVE-2011-1770
Published: 24 June 2011
Integer underflow in the dccp_parse_options function (net/dccp/options.c) in the Linux kernel before 2.6.33.14 allows remote attackers to cause a denial of service via a Datagram Congestion Control Protocol (DCCP) packet with an invalid feature options length, which triggers a buffer over-read.
From the Ubuntu Security Team
Dan Rosenberg discovered that the DCCP stack did not correctly handle certain packet structures. A remote attacker could exploit this to crash the system, leading to a denial of service.
