"The remote host is affected by the vulnerability described in GLSA-200409-24
(Foomatic: Arbitrary command execution in foomatic-rip filter)

    There is a vulnerability in the foomatic-filters package. This
    vulnerability is due to insufficient checking of command-line parameters
    and environment variables in the foomatic-rip filter.
  
Impact :

    This vulnerability may allow both local and remote attackers to execute
    arbitrary commands on the print server with the permissions of the spooler
    (oftentimes the 'lp' user).
  
Workaround :

    There is no known workaround at this time."
