Updated libexif packages that fix a security issue are now available for
Red Hat Enterprise Linux 4.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
The libexif packages contain the Exif library. Exif is an image file format
specification that enables metadata tags to be added to existing JPEG, TIFF
and RIFF files. The Exif library makes it possible to parse an Exif file
and read this metadata.
An integer overflow flaw was found in the way libexif parses Exif image
tags. If a victim opens a carefully crafted Exif image file, it could cause
the application linked against libexif to execute arbitrary code, or crash.
Users of libexif are advised to upgrade to these updated packages, which
contain a backported patch to resolve this issue.
