Debian DLA-249-1 : qemu-kvm security update (Venom)

high Nessus Plugin ID 84295

Language:

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-kvm support in the old-oldstable distribution (squeeze-lts), this problem has been fixed in version 0.12.5+dfsg-5+squeeze11 of the qemu-kvm source package due to its severity (the so-called VENOM vulnerability).

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

We recommend that you upgrade your qemu-kvm 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 kvm, qemu-kvm, and qemu-kvm-dbg packages.
