May Allow Code Execution or a Denial of Service (DoS) Condition
Bug ID: 6652301
Product
Solaris 10 Operating System
Date of Resolved Release: 18-Mar-2008
SA Document Body
A Security Vulnerability in Solaris 10 libexif (see below for details):
1. Impact
A security vulnerability in the libexif image processing library
shipped with Solaris 10 may allow a remote unprivileged user who
provides an image with a crafted EXIF tag to execute arbitrary code
with the privileges of a local user who opens that image. Furthermore,
a remote user may be able to cause a Denial of Service (DoS) to an
application that reads a crafted EXIF image using the libexif library.
This issue may occur with applications linked against the libexif
library including (but not limited to), the Eye of Gnome (eog(1))
application, which is distributed as part of the Java Desktop System.
