Synopsis
=======
Multiple insecure temporary file vulnerabilities have been discovered
in the Website META Language.

Background
=========
Website META Language is a free and extensible Webdesigner's off-line
HTML generation toolkit for Unix.

Affected packages
================
    -------------------------------------------------------------------
     Package       /   Vulnerable   /                       Unaffected
    -------------------------------------------------------------------
  1  dev-lang/wml      < 2.0.11-r3                        >= 2.0.11-r3

Description
==========
Temporary files are handled insecurely in the files
wml_backend/p1_ipp/ipp.src, wml_contrib/wmg.cgi, and
wml_backend/p3_eperl/eperl_sys.c, allowing users to overwrite or delete
arbitrary files with the privileges of the user running the program.

Impact
=====
Local users can exploit the insecure temporary file vulnerabilities via
symlink attacks to perform certain actions with escalated privileges.

Workaround
=========
Restrict access to the temporary directory to trusted users only.

Resolution
=========
All Website META Language users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-lang/wml-2.0.11-r3"
