    Multiple vulnerabilities have been discovered in Perl. Please review the
      CVE identifiers referenced below for details.
  
Impact :

    A local attacker could cause a Denial of Service condition or perform
      symlink attacks to overwrite arbitrary files with the privileges of the
      user running the application. A context-dependent attacker could cause a
      Denial of Service condition.
  
Workaround :

    There is no known workaround at this time."
