The remote host is missing updates announced in advisory RHSA-2007:1166.
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. (CVE-2007-6352)
Users of libexif are advised to upgrade to these updated packages, which contain a backported patch to resolve this issue.
