Synopsis ========
KPdf and KOffice 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. KOffice is an integrated office suite for KDE.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-office/koffice < 1.3.5-r2 >= 1.3.5-r2 2 kde-base/kdegraphics < 3.3.2-r2 >= 3.3.2-r2 *>= 3.2.3-r4 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. -------------------------------------------------------------------
Description ===========
KPdf and KOffice both include Xpdf code to handle PDF files. Xpdf is vulnerable to a new stack overflow, as described in GLSA 200501-28.
Impact ======
An attacker could entice a user to open a specially-crafted PDF file, 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 KPdf users should upgrade to the latest version of kdegraphics:
# emerge --sync # emerge --ask --oneshot --verbose kde-base/kdegraphics
All KOffice users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose app-office/koffice
