Mandrake Linux Security Advisory : gzip (MDKSA-2003:068)

This script is Copyright (C) 2004-2013 Tenable Network Security, Inc.


Synopsis :

The remote Mandrake Linux host is missing a security update.

Description :

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.
