Severity:	normal
Title:	KOffice, KWord: RTF import buffer overflow
Date:	10/14/2005
Bugs:	#108411
ID:	200510-12

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	Architecture(s)
app-office/koffice	< 1.4.1-r1	>= 1.4.1-r1	All supported architectures
app-office/kword	< 1.4.1-r1	>= 1.4.1-r1	All 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"
