libexif is a library for parsing, editing and saving Exif metadata from images. Exif, the Exchangeable image file format, specifies the addition of metadata tags to JPEG, TIFF and RIFF files.
Meder Kydyraliev (Google Security) discovered an integer overflow vulnerability in the exif_data_load_data_thumbnail() function leading to a memory corruption (CVE-2007-6352) and an infinite recursion in the exif_loader_write() function (CVE-2007-6351).
An attacker could entice the user of an application making use of libexif to load an image file with specially crafted Exif tags, possibly resulting in the execution of arbitrary code with the privileges of the user running the application or a Denial of Service.
There is no known workaround at this time.
All libexif users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/libexif-0.6.16-r1"
