(gzip: Insecure creation of temporary files)

    The script gzexe included with gzip contains a bug in the code that
    handles tempfile creation. If the creation of a temp file fails when
    using gzexe fails instead of bailing out it executes the command given
    as argument.
  
Impact :

    This could lead to privilege escalation by running commands under the
    rights of the user running the self-extracting file.
  
Workaround :

    There is no known workaround at this time. All users are encouraged to
    upgrade to the latest available version."

    # emerge '>=app-arch/gzip-1.3.3-r4'
    Additionally, once the upgrade is complete, all self-extracting files
    created with earlier versions gzexe should be recreated, since the
    vulnerability is actually embedded in those executables."
