CVE-2012-5513

Name of the Vulnerable Software and Affected Versions Xen versions prior to 4.2

Description The issue is related to the XENMEM exchange handler, which does not properly check the memory address. This allows local PV guest OS administrators to cause a denial of service (crash) or possibly gain privileges via unspecified vectors that overwrite memory in the hypervisor reserved range.

Recommendations For Xen versions prior to 4.2, update to a version that includes the fix for this issue to prevent potential denial of service or privilege escalation.
