Debian DLA-248-1 : qemu security update (Venom)

high Nessus Plugin ID 84294
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 update.

Description

A vulnerability was discovered in the qemu virtualisation solution :

CVE-2015-3456

Jason Geffner discovered a buffer overflow in the emulated floppy disk drive, resulting in the potential execution of arbitrary code.

Despite the end-of-life of qemu support in the old-oldstable distribution (squeeze-lts), this problem has been fixed in version 0.12.5+dfsg-3squeeze4 of the qemu source package due to its severity (the so-called VENOM vulnerability).

Further problems may still be present in the qemu package in the old-oldstable distribution (squeeze-lts) and users who need to rely on qemu are encouraged to upgrade to a newer version of Debian.

We recommend that you upgrade your qemu packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
