A heap-based buffer overflow in Okular might allow a remote attacker to execute arbitrary code or cause a Denial of Service condition.
|Package||kde-base/okular on all architectures|
|Affected versions||< 4.4.5-r2|
|Unaffected versions||>= 4.4.5-r2|
Okular is a universal document viewer based on KPDF for KDE 4.
Okular contains a heap-based buffer overflow in the RLE decompression functionality in the TranscribePalmImageToJPEG function in generators/plucker/inplug/image.cpp.
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.
There is no known workaround at this time.
All Okular users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=kde-base/okular-4.4.5-r2"
