ELA-299-1 spice-gtk security update

multiple buffer overflow

Related CVEs CVE-2020-14355

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 8 jessie, these problems have been fixed in version 0.25-1+deb8u2.

We recommend that you upgrade your spice-gtk packages.
