Stefan Cornelius of Secunia Research discovered a boundary error during
RLE decompression in the "TranscribePalmImageToJPEG()" function in
generators/plucker/inplug/image.cpp of okular when processing images
embedded in PDB files, which can be exploited to cause a heap-based
buffer overflow. (CVE-2010-2575)
The problem can be corrected by updating your system to the following package version:

After a standard system update you need to restart any running instances
of okular to make all the necessary changes.
