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:
