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 Debian 7 Wheezy, these problems have been fixed in version 0.11.0-1+deb7u4.

We recommend that you upgrade your spice packages.
