Debian DSA-3354-1 : spice - security update

medium Nessus Plugin ID 85851

Language:

Synopsis

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

Description

Frediano Ziglio of Red Hat discovered a race condition flaw in spice's worker_update_monitors_config() function, leading to a heap-based memory corruption. A malicious user in a guest can take advantage of this flaw to cause a denial of service (QEMU process crash) or, potentially execute arbitrary code on the host with the privileges of the hosting QEMU process.

Solution

Upgrade the spice packages.

For the stable distribution (jessie), this problem has been fixed in version 0.12.5-1+deb8u1.
