for details) :
1. Impact
A remote unprivileged user may be able to crash an application which
dynamically links to the Portable Network Graphics library (libpng(3))
due to a security vulnerability in libpng(3). The ability to crash an
application is a type of Denial of Service (DoS). A number of
applications which comprise the GNOME desktop environment dynamically
link with libpng(3).
This issue is described in the following documents:
* CERT VU# 684664 at: https://www.kb.cert.org/vuls/id/684664

the following command can be run:
% grep distributor-version /usr/share/gnome-about/gnome-version.xml
<distributor-version>Sun Java Desktop System, Release 2</distributor-version>
3. Symptoms
If the described issue occurs, the application which links to the
libpng(3) library will exit and may generate an error message about a
Segmentation Fault and may also write a core(4) file.

sources.
