|Gentoo Linux Security Advisory
Title: Okular: Arbitrary code execution (GLSA 201311-20)
Date: November 28, 2013
A heap-based buffer overflow in Okular might allow a remote
attacker to execute arbitrary code or cause a Denial of Service condition.
Okular is a universal document viewer based on KPDF for KDE 4.
Vulnerable: < 4.4.5-r2
Unaffected: >= 4.4.5-r2
Architectures: All supported architectures
Okular contains a heap-based buffer overflow in the RLE decompression
functionality in the TranscribePalmImageToJPEG function in
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"
