The remote host is affected by the vulnerability described in GLSA-200710-08 (KOffice, KWord, KPDF, KDE Graphics Libraries: Stack-based buffer overflow)
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.
