Detailsinfo

A vulnerability has been found in Linux Foundation Xen up to 4.2.2 (Virtualization Software) and classified as problematic. Affected by this vulnerability is an unknown part of the component Table Manipulation Operations Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect availability. The summary by CVE is:

Certain page table manipulation operations in Xen 4.1.x, 4.2.x, and earlier are not preemptible, which allows local PV kernels to cause a denial of service via vectors related to "deep page table traversal."

The weakness was shared 05/02/2013 as not defined mailinglist post (oss-sec). It is possible to read the advisory at seclists.org. The vendor cooperated in the coordination of the public release. This vulnerability is known as CVE-2013-1918 since 02/19/2013. Attacking locally is a requirement. The exploitation doesn't need any form of authentication. The technical details are unknown and an exploit is not publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 79505 (OracleVM 3.2 : xen (OVMSA-2013-0036)), which helps to determine the existence of the flaw in a target environment.
