Synopsis
========

A buffer overflow in Pango might allow an attacker to execute arbitrary
code.

Background
==========

Pango is a library for layout and rendering of internationalized text.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 x11-libs/pango < 1.42.4-r2 >= 1.42.4-r2

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

A buffer overflow has been discovered in Pango's
pango_log2vis_get_embedding_levels function.

Impact
======

A remote attacker could entice a user to process a specially crafted
string with functions like pango_itemize, possibly resulting in
execution of arbitrary code with the privileges of the process or a
Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Pango users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-libs/pango-1.42.4-r2"
