MDKSA-2003:068: gzip Vulnerability Scan

Vulnerability Scan Summary
Check for the version of the gzip package

Detailed Explanation for this Vulnerability Test

The remote host is missing the patch for the advisory MDKSA-2003:068 (gzip).

A vulnerability exists in znew, a script included with gzip, that would create
temporary files without taking precautions to avoid a symlink attack. Patches
have been applied to make use of mktemp to generate unique filenames, and
properly make use of noclobber in the script. Likewise, a fix for gzexe which
had been applied previously was incomplete. It has been fixed to make full use
of mktemp everywhere a temporary file is created.
The znew problem was initially reported by Michal Zalewski and was again
reported more recently to Debian by Paul Szabo.
