Debian Security Advisory

DLA-1489-1 spice-gtk -- LTS security update

Date Reported:
31 Aug 2018
Affected Packages:
spice-gtk
Vulnerable:
Yes
Security database references:
In the Debian bugtracking system: Bug 906316.
In Mitre's CVE dictionary: CVE-2018-10873.
More information:

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.

The above issue and fix have already been announced for the spice Debian package (as DLA-1486-1 [1]). This announcement is about the "spice-gtk" Debian package (which ships some copies of code from the spice package, where the fix of this issue had to be applied).

For Debian 8 Jessie, this problem has been fixed in version 0.25-1+deb8u1.

We recommend that you upgrade your spice-gtk packages.
