Debian DSA-3045-1 : qemu - security update

high Nessus Plugin ID 78046
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

Several vulnerabilities were discovered in qemu, a fast processor emulator :

- Various security issues have been found in the block qemu drivers. Malformed disk images might result in the execution of arbitrary code.
- A NULL pointer dereference in SLIRP may result in denial of service

- An information leak was discovered in the VGA emulation

Solution

Upgrade the qemu packages.

For the stable distribution (wheezy), these problems have been fixed in version 1.1.2+dfsg-6+deb7u4.
