Description:   A buffer overflow vulnerability was reported in libexif. A remote user may be able to cause a target user's application to crash or execute arbitrary code.

The exif library does not properly validate user-supplied input in several places. A remote user can create a specially crafted JPEG image with invalid EXIF header data. When the image is loaded by the target user's application that uses libexif, the application may crash or potentially execute arbitrary code.

The flaw resides in 'exif-data.c'.

Sylvain Defresne discovered this vulnerability.

Impact:   A remote user can create an image file that, when loaded by the target user's application, will cause the application to crash or potentially execute arbitrary code.
Solution:   The vendor has issued a patch, available at:
