Synopsis ========
KPdf includes vulnerable Xpdf code to handle PDF files, making it vulnerable to the execution of arbitrary code.
Background ==========
KPdf is a KDE-based PDF viewer included in the kdegraphics package.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 kde-base/kdegraphics < 3.4.3-r4 >= 3.4.3-r4 2 kde-base/kpdf < 3.4.3-r4 >= 3.4.3-r4 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. -------------------------------------------------------------------
Description ===========
KPdf includes Xpdf code to handle PDF files. Dirk Mueller discovered that the Xpdf code is vulnerable a heap based overflow in the splash rasterizer engine.
Impact ======
An attacker could entice a user to open a specially crafted PDF file with Kpdf, 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:
# emerge --sync # emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-3.4.3-r4"
All Kpdf users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=kde-base/kpdf-3.4.3-r4"
