New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 5.9

Synopsis

The remote Debian host is missing a security-related update.

Description

Michael S. Tsirkin of Red Hat discovered a buffer overflow flaw in the way qemu processed MAC addresses table update requests from the guest.

A privileged guest user could use this flaw to corrupt qemu process memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the qemu process.

Solution

Upgrade the qemu packages.

For the oldstable distribution (squeeze), this problem has been fixed in version 0.12.5+dfsg-3squeeze4.

For the stable distribution (wheezy), this problem has been fixed in version 1.1.2+dfsg-6+deb7u1.
