The generated demarshalling code is prone to multiple buffer overflows. An authenticated attacker can take advantage of this flaw to cause a denial of service (spice server crash), or possibly, execute arbitrary code.

For the stable distribution (stretch), this problem has been fixed in version 0.12.8-2.1+deb9u2.

We recommend that you upgrade your spice packages.

For the detailed security status of spice please refer to its security tracker page at: [link moved to references]");
