[GLSA]

Gentoo Linux Security Advisory

Title: KPdf, KWord: Multiple overflows in included Xpdf code (GLSA 200601-02)
Severity: normal
Exploitable: remote
Date: January 04, 2006
Updated: January 07, 2006
Bug(s): #114429, #115851
ID: 200601-02

Synopsis


KPdf and KWord both include vulnerable Xpdf code to handle PDF files,
making them vulnerable to the execution of arbitrary code.


Background


KPdf is a KDE-based PDF viewer included in the kdegraphics package.
KWord is a KDE-based word processor also included in the koffice
package.


Affected Packages

Package: kde-base/kdegraphics
Vulnerable: < 3.4.3-r3
Unaffected: >= 3.4.3-r3
Architectures: All supported architectures

Package: kde-base/kpdf
Vulnerable: < 3.4.3-r3
Unaffected: >= 3.4.3-r3
Architectures: All supported architectures

Package: app-office/koffice
Vulnerable: < 1.4.2-r6
Unaffected: >= 1.4.2-r6
Architectures: All supported architectures

Package: app-office/kword
Vulnerable: < 1.4.2-r6
Unaffected: >= 1.4.2-r6
Architectures: All supported architectures


Description


KPdf and KWord both include Xpdf code to handle PDF files. This Xpdf
code is vulnerable to several heap overflows (GLSA 200512-08) as well
as several buffer and integer overflows discovered by Chris Evans
(CESA-2005-003).


Impact


An attacker could entice a user to open a specially crafted PDF file
with Kpdf or KWord, 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 kdegraphics users should upgrade to the latest version:
