Synopsis
========
KOffice and KWord are vulnerable to a buffer overflow in the RTF
importer, potentially resulting in the execution of arbitrary code.
Background
==========
KOffice is an integrated office suite for KDE. KWord is the KOffice
word processor.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-office/koffice < 1.4.1-r1 >= 1.4.1-r1
2 app-office/kword < 1.4.1-r1 >= 1.4.1-r1
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
===========
Chris Evans discovered that the KWord RTF importer was vulnerable to a
heap-based buffer overflow.
Impact
======
An attacker could entice a user to open a specially-crafted RTF file,
potentially resulting in the execution of arbitrary code with the
rights of the user running the affected application.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All KOffice users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/koffice-1.4.1-r1"
All KWord users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/kword-1.4.1-r1"
