Synopsis
=======

A buffer overflow in UnRTF allows an attacker to execute arbitrary code by way of a specially crafted RTF file.

Background
=========

UnRTF is a utility to convert files in the Rich Text Format into other formats.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-text/unrtf < 0.19.3-r1 >= 0.19.3-r1

Description
==========

An unchecked strcat() in unrtf may overflow the bounds of a static buffer.

Impact
=====

Using a specially crafted file, possibly delivered by e-mail or over the web, an attacker may execute arbitrary code with the permissions of the user running UnRTF.

Workaround
=========

There is no known workaround at this time.

Resolution
=========

All unrtf users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/unrtf-0.19.3-r1"
