CRITICAL:
Less critical

IMPACT:
Security Bypass

WHERE:
Local system

SOFTWARE:
libvirt 0.x
http://secunia.com/advisories/product/20813/

DESCRIPTION:
A security issue has been reported in libvirt, which can be exploited
by malicious, local users to bypass certain security restrictions.

The security issue is caused due to the application not properly
checking if a connection to libvirtd is in read-only or read-write
mode. This can be exploited to perform certain administrative tasks
by using methods, which are not performing checks on the read-only
connection flag.

This security issue is reported in version 0.3.2 through 0.5.1. Other
versions may also be affected.

SOLUTION:
Fixed in the CVS and GIT repositories.
