Severity: Normal
Title: Website META Language: Insecure temporary file usage
Date: March 15, 2008
Bugs: #209927
ID: 200803-23

---

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"
