Description

This security bulletin contains information about 1 security vulnerability.


1) Configuration (CVE-ID: CVE-2012-4537)

The vulnerability allows a local non-authenticated attacker to perform service disruption.

Xen 3.4 through 4.2, and possibly earlier versions, does not properly synchronize the p2m and m2p tables when the set_p2m_entry function fails, which allows local HVM guest OS administrators to cause a denial of service (memory consumption and assertion failure), aka "Memory mapping failure DoS vulnerability."


Remediation

Install update from vendor's website.
