KOffice, KWord: RTF import buffer overflow

Background

KOffice is an integrated office suite for KDE. KWord is the KOffice word processor.

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"
