Debian DSA-1735-1 : znc - missing input sanitization

medium Nessus Plugin ID 35901

Synopsis

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

Description

It was discovered that znc, an IRC proxy/bouncer, does not properly sanitize input contained in configuration change requests to the webadmin interface. This allows authenticated users to elevate their privileges and indirectly execute arbitrary commands (CVE-2009-0759 ).

Solution

Upgrade the znc packages.

For the old stable distribution (etch), this problem has been fixed in version 0.045-3+etch2.

For the stable distribution (lenny), this problem has been fixed in version 0.058-2+lenny1.
