Overview
CVE-2010-2784 is a medium-severity vulnerability affecting redhat enterprise_virtualization. It was published on August 24, 2010 and has a CVSS 2.0 base score of 6.6 (MEDIUM).
This vulnerability has a CVSS 2.0 base score of 6.6, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical description
The subpage MMIO initialization functionality in the subpage_register function in exec.c in QEMU-KVM, as used in the Hypervisor (aka rhev-hypervisor) in Red Hat Enterprise Virtualization (RHEV) 2.2 and KVM 83, does not properly select the index for access to the callback array, which allows guest OS users to cause a denial of service (guest OS crash) or possibly gain privileges via unspecified vectors.
Remediation
Check the references section for vendor advisories and patches from redhat. Update enterprise_virtualization 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.
