tag_impact = "Successful exploitation will allow attackers to cause an affected
  application to crash, denying service to legitimate users.
  Impact Level: Application";

tag_insight = "The flaw is due to an error in 'getpeername', 'readdir', 'closedir',
  'getsockname', 'rewinddir', 'tell', or 'telldir' function calls. When given
  a wrong number of arguments, those functions will attempt to perform a
  comparison between an unallocated memory zone and a given register, resulting
  in a segmentation fault.";

  For updates refer to http://www.perl.org/get.html";
