Synopsis
========
A buffer overflow in o3read allows an attacker to execute arbitrary
code by way of a specially crafted XML file.
Background
==========
o3read is a standalone converter for OpenOffice.org files. It allows a
user to dump the contents tree (o3read) and convert to plain text
(o3totxt) or to HTML (o3tohtml) Writer and Calc files.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-text/o3read <= 0.0.3 >= 0.0.4
Description
===========
Wiktor Kopec discovered that the parse_html function in o3read.c copies
any number of bytes into a 1024-byte t[] array.
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 o3read.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All o3read users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/o3read-0.0.4"
