Several vulnerabilities were discovered in spice, a SPICE protocol client and server library

Summary

CVE-2016-9577

Frediano Ziglio of Red Hat discovered a buffer overflow
vulnerability in the main_channel_alloc_msg_rcv_buf function. An
authenticated attacker can take advantage of this flaw to cause a
denial of service (spice server crash), or possibly, execute
arbitrary code.

CVE-2016-9578

Frediano Ziglio of Red Hat discovered that spice does not properly
validate incoming messages. An attacker able to connect to the
spice server could send crafted messages which would cause the
process to crash.

For the stable distribution (jessie), these problems have been fixed in
version 0.12.5-1+deb8u4.

For the unstable distribution (sid), these problems have been fixed in
version 0.12.8-2.1.

We recommend that you upgrade your spice packages.
