Detail

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).

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.

For the unstable distribution (sid), this problem has been fixed in version 0.066-1.

We recommend that you upgrade your znc packages.
