The remote host is missing an update for the Debian 'znc' package(s) announced via the DSA-1735-1 advisory. znc, an IRC proxy/bouncer, does not properly sanitize input contained in configuration change requests to the webadmin interface, allowing authenticated users to elevate their privileges and indirectly execute arbitrary commands (CVE-2009-0759). Solution: Please install the updated package(s)
