debian lts
November 1, 2020
Multiple buffer overflow vulnerabilities were found in the QUIC image decoding process of the SPICE remote display system, before spice-0.14.2-1
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
0.12.8-2.1+deb9u4.
We recommend that you upgrade your spice packages.
