Description:

Advchk is a tool for monitoring the security of installed
software. Advisory Check gathers security advisories using RSS/RDF/XML
feeds, compares them against a list of known software, and alerts you
if you're vulnerable. Since adding software lists by hand would be
quite a boring task, advchk leverages your system's package manager
for detecting software. Software installed on remote systems can be
monitored through nmap scans or by executing the remote package
manager as an SSH ForcedCommand using Public-key authentication.
