Debian DLA-825-1 : spice security update

high Nessus Plugin ID 97216

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
