KOffice, KWord, KPDF, KDE Graphics Libraries: Stack-based buffer overflow

KOffice, KWord, KPDF, KDE Graphics Libraries: Stack-based buffer overflow KPDF includes code from xpdf that is vulnerable to a stack-based buffer overflow. koffice, kword, kdegraphics, kpdf 2007-10-09 2007-10-09 187139 remote 1.6.3-r1 1.6.3-r1 1.6.3-r1 1.6.3-r1 3.5.7-r1 3.5.7-r1 3.5.7-r1 3.5.7-r1

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.

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

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.

There is no known workaround at this time.

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"
