Debian DLA-2427-1 : spice security update

medium Nessus Plugin ID 142158

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Multiple buffer overflow vulnerabilities were found in the QUIC image decoding process of the SPICE remote display system, before spice-0.14.2-1.

Both the SPICE client (spice-gtk) and server are affected by these flaws. These flaws allow a malicious client or server to send specially crafted messages that, when processed by the QUIC image compression algorithm, result in a process crash or potential code execution.

For Debian 9 stretch, this problem has been fixed in version 0.12.8-2.1+deb9u4.

We recommend that you upgrade your spice packages.

For the detailed security status of spice please refer to its security tracker page at: https://security-tracker.debian.org/tracker/spice

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.
