CVE-2014-8867 is a medium-severity vulnerability affecting redhat enterprise_linux. It was published on December 1, 2014 and has a CVSS 2.0 base score of 4.9 (MEDIUM).
This vulnerability has a CVSS 2.0 base score of 4.9, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
The acceleration support for the "REP MOVS" instruction in Xen 4.4.x, 3.2.x, and earlier lacks properly bounds checking for memory mapped I/O (MMIO) emulated in the hypervisor, which allows local HVM guests to cause a denial of service (host crash) via unspecified vectors.
Remediation
Check the references section for vendor advisories and patches from redhat. Update enterprise_linux to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
