Package : spice
Version : 0.11.0-1+deb7u4
CVE ID : CVE-2016-9577 CVE-2016-9578
Debian Bug : 854336

Several vulnerabilities were discovered in spice, a SPICE protocol
client and server library. The Common Vulnerabilities and Exposures
project identifies the following problems:

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.
