Heap-based buffer overflow in the RLE decompression functionality in the TranscribePalmImageToJPEG function in generators/plucker/inplug/image.cpp in Okular in KDE SC 4.3.0 through 4.5.0 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted image in a PDB file.

This update fixes a heap-based overflow in okular. The RLE decompression in the TranscribePalmImageToJPEG() function can be exploited to execute arbitrary code with user privileges by providing a crafted PDF file. (CVE-2010-2575).

The remote host is affected by the vulnerability described in GLSA-201311-20 (Okular: Arbitrary code execution)

    Okular contains a heap-based buffer overflow  in the RLE decompression       functionality in the TranscribePalmImageToJPEG function in       generators/plucker/inplug/image.cpp.
  Impact :

    A remote attacker could entice a user to open a specially crafted PBD       file using Okular, possibly resulting in execution of arbitrary code with       the privileges of the process, or a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

New kdegraphics packages are available for Slackware 13.1 to fix a security issue in the okular document viewer.

This update fixes a heap-based overflow in okular. The RLE decompression in the TranscribePalmImageToJPEG() function can be exploited to execute arbitrary code with user privileges by providing a crafted PDF file. (CVE-2010-2575)

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).

A vulnerability has been found and corrected in okular (kdegraphics) :

A specially crafted PDF or PS file could cause okular to crash or execute arbitrary code (CVE-2010-2575).

The updated packages have been patched to correct this issue.
