medium Nessus Plugin ID 55625

Synopsis

The remote Debian host is missing a security-related update.

Description

It was discovered that libvirt, a library for interfacing with different virtualization systems, is prone to an integer overflow (CVE-2011-2511 ). Additionally, the stable version is prone to a denial of service, because its error reporting is not thread-safe (CVE-2011-1486 ).

Solution

Upgrade the libvirt packages.

For the stable distribution (squeeze), these problems have been fixed in version 0.8.3-5+squeeze2.

For the oldstable distribution (lenny), this problem has been fixed in version 0.4.6-10+lenny2.
