Summary

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.
