Synopsis
========

Multiple vulnerabilities have been found in SWI-Prolog which allow
attackers to execute arbitrary code or cause a Denial of Service
condition.

Background
==========

SWI-Prolog is a free, small, and standard compliant Prolog compiler.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-lang/swi-prolog < 6.2.5 >= 6.2.5

Description
===========

Multiple vulnerabilities have been discovered in SWI-Prolog:
* An error in the canoniseFileName() function could cause a stack-based
buffer overflow (CVE-2012-6089).
* An error in the expand() function could cause a stack-based buffer
overflow (CVE-2012-6090).

Impact
======

A context-dependent attack can create files with specially crafted
names, causing arbitrary code execution or a denial of service
condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All SWI-Prolog users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/swi-prolog-6.2.5"
