Gentoo Linux Security Advisory

Title: KOffice, KWord, KPDF, KDE Graphics Libraries: Stack-based buffer overflow (GLSA 200710-08)
Severity: normal
Exploitable: remote
Date: October 09, 2007
Bug(s): #187139
ID: 200710-08

Synopsis

KPDF includes code from xpdf that is vulnerable to a stack-based buffer overflow.

Background

KOffice is an integrated office suite for KDE. KWord is the KOffice word processor. KPDF is a KDE-based PDF viewer included in the kdegraphics package.

Affected Packages

Package: app-office/koffice
Vulnerable: < 1.6.3-r1
Unaffected: >= 1.6.3-r1
Architectures: All supported architectures

Package: app-office/kword
Vulnerable: < 1.6.3-r1
Unaffected: >= 1.6.3-r1
Architectures: All supported architectures

Package: kde-base/kdegraphics
Vulnerable: < 3.5.7-r1
Unaffected: >= 3.5.7-r1
Architectures: All supported architectures

Package: kde-base/kpdf
Vulnerable: < 3.5.7-r1
Unaffected: >= 3.5.7-r1
Architectures: All supported architectures


Description

KPDF includes code from xpdf that is vulnerable to an integer overflow in the StreamPredictor::StreamPredictor() function.

Impact

A remote attacker could entice a user to open a specially crafted PDF file in KWord or KPDF that would exploit the integer overflow to cause a stack-based buffer overflow in the StreamPredictor::getNextLine() function, possibly resulting in the execution of arbitrary code with the privileges of the user running the application.

Workaround

There is no known workaround at this time.

Resolution

All KOffice users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/koffice-1.6.3-r1"
All KWord users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/kword-1.6.3-r1"
All KDE Graphics Libraries users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-3.5.7-r1"
All KPDF users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-base/kpdf-3.5.7-r1"
