| Severity: | normal | 
| Title: | Okular: Arbitrary code execution | 
| Date: | 11/28/2013 | 
| Bugs: | |
| ID: | 201311-20 | 
Synopsis
A heap-based buffer overflow in Okular might allow a remote attacker to execute arbitrary code or cause a Denial of Service condition.Background
Okular is a universal document viewer based on KPDF for KDE 4.
Affected packages
| Package | Vulnerable | Unaffected | Architecture(s) | 
|---|---|---|---|
| kde-base/okular | < 4.4.5-r2 | >= 4.4.5-r2 | All supported architectures | 
Description
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.
Resolution
All Okular users should upgrade to the latest version:
      # emerge --sync
      # emerge --ask --oneshot --verbose ">=kde-base/okular-4.4.5-r2"
