Detailsinfo

A vulnerability was found in Linux Kernel 2.6.16.9 (Operating System). It has been rated as problematic. This issue affects the function wait_for_unix_gc. The manipulation with an unknown input leads to a resource management vulnerability. Using CWE to declare the problem leads to CWE-399. Impacted is availability. The summary by CVE is:

The wait_for_unix_gc function in net/unix/garbage.c in the Linux kernel before 2.6.37-rc3-next-20101125 does not properly select times for garbage collection of inflight sockets, which allows local users to cause a denial of service (system hang) via crafted use of the socketpair and sendmsg system calls for SOCK_SEQPACKET sockets.

The issue has been introduced in 03/20/2006. The weakness was published 11/29/2010 by Key Night as Bug 656756 as confirmed bug report (Bugzilla). The advisory is shared at bugzilla.redhat.com. The identification of this vulnerability is CVE-2010-4249. The exploitation is known to be easy. An attack has to be approached locally. No form of authentication is needed for a successful exploitation. Technical details as well as a public exploit are known.

A public exploit has been developed by Key Night in ANSI C and been published even before and not after the advisory. The exploit is available at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1707 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 68207 (Oracle Linux 5 : kernel (ELSA-2011-0303)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Oracle Linux Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 155554 (Oracle Enterprise Linux Update for Kernel (ELSA-2011-0162)).

A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (63439), Exploit-DB (15622), Tenable (68207), SecurityFocus (BID 45037†) and OSVDB (69527†). Similar entries are available at VDB-55569, VDB-55568, VDB-55567 and VDB-55566. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
