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"
