Affected Packages:

spice-gtk

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 971751.
In Mitre's CVE dictionary: CVE-2020-14355.

More information:

Multiple buffer overflow vulnerabilities were found in the QUIC image decoding process of the SPICE remote display system.

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 0.33-3.3+deb9u2.

We recommend that you upgrade your spice-gtk packages.
