  <title>gettext: Insecure temporary file handling</title>
  <synopsis>
    The gettext utility is vulnerable to symlink attacks, potentially allowing
    a local user to overwrite or change permissions on arbitrary files with the
    rights of the user running gettext, which could be the root user.

    <p>
    gettext is a set of utilities for the GNU Translation Project which
    provides a set of tools and documentation to help produce multi-lingual
    messages in programs.
    </p>
  </background>
  <description>
    <p>
    gettext insecurely creates temporary files in world-writeable
    directories with predictable names.
    </p>
  </description>
  <impact type="low">
    <p>
    A local attacker could create symbolic links in the temporary files
    directory, pointing to a valid file somewhere on the filesystem. When
    gettext is called, this would result in file access with the rights of
    the user running the utility, which could be the root user.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All gettext users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=sys-devel/gettext-0.14.1-r1&quot;</code>
  </resolution>
