Debian DLA-1486-1 : spice security update

high Nessus Plugin ID 112225

Synopsis

The remote Debian host is missing a security update.

Description

A vulnerability was discovered in SPICE before version 0.14.1 where the generated code used for demarshalling messages lacked sufficient bounds checks. A malicious client or server, after authentication, could send specially crafted messages to its peer which would result in a crash or, potentially, other impacts.

The issue has been fixed by upstream by bailing out with an error if the pointer to the start of some message data is strictly greater than the pointer to the end of the message data.

For Debian 8 'Jessie', this problem has been fixed in version 0.12.5-1+deb8u6.

We recommend that you upgrade your spice 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.
