CVE-2010-4805  (opens in a new tab)
CWE-400  (opens in a new tab)

How to fix?

Upgrade Centos:6 kernel-headers to version 0:2.6.32-71.31.1.el6 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-headers package and not the kernel-headers package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

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.
