Severity: Normal Title: KOffice, KWord, KPDF, KDE Graphics Libraries: Stack-based buffer overflow Date: October 09, 2007 Bugs: #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 / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-office/koffice < 1.6.3-r1 >= 1.6.3-r1 2 app-office/kword < 1.6.3-r1 >= 1.6.3-r1 3 kde-base/kdegraphics < 3.5.7-r1 >= 3.5.7-r1 4 kde-base/kpdf < 3.5.7-r1 >= 3.5.7-r1 ------------------------------------------------------------------- 4 affected packages on all of their 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:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-office/koffice-1.6.3-r1"
All KWord users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-office/kword-1.6.3-r1"
All KDE Graphics Libraries users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-3.5.7-r1"
All KPDF users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=kde-base/kpdf-3.5.7-r1"
