Description

This update to the latest upstream release fixes a number of bugs, among them a possible integer overflow in the exif_data_load_data_entry function (CVE-2007-2645), which allows user-assisted remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted EXIF data.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
