CVE-2010-4805
Published: 26 May 2011
The socket implementation in net/core/sock.c in the Linux kernel before 2.6.35 does not properly manage a backlog of received packets, which allows remote attackers to cause a denial of service by sending a large amount of network traffic, related to the sk_add_backlog function and the sk_rmem_alloc socket field. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-4251.
From the Ubuntu Security Team
Alex Shi and Eric Dumazet discovered that the network stack did not correctly handle packet backlogs. A remote attacker could exploit this by sending a large amount of network traffic to cause the system to run out of memory, leading to a denial of service.
