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"
