Synopsis
========

AbiWord is vulnerable to a stack-based buffer overflow during RTF
import, making it vulnerable to the execution of arbitrary code.

Background
==========

AbiWord is a free and cross-platform word processing program. It allows
to import RTF files into AbiWord documents.

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

    -------------------------------------------------------------------
     Package             /  Vulnerable  /                   Unaffected
    -------------------------------------------------------------------
  1  app-office/abiword      < 2.2.10                        >= 2.2.10

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

Chris Evans discovered that the RTF import function in AbiWord is
vulnerable to a stack-based buffer overflow.

Impact
======

An attacker could design a malicious RTF file and entice the user to
import it in AbiWord, potentially resulting in the execution of
arbitrary code with the rights of the user running AbiWord.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All AbiWord users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-office/abiword-2.2.10"
