Description:
A vulnerability has been reported in KDE, which can be exploited by malicious people to cause a DoS (Denial of Service) on a user's system.
The vulnerability is caused due to an error in kpdf when verifying the validity in of the "loca" table in a PDF file. This can be exploited to cause kpdf to create an overly large temporary file when attempting to reconstruct the table in a specially crafted PDF document.
Successful exploitation may cause all available disk space to be exhausted.
The vulnerability affects versions 3.3.1 through 3.4.1.
Solution:
Apply patches.
