This flaw allows an unauthenticated attacker or authenticated attacker with low privileges to exploit the flaw remotely in an application that uses libexif to process EXIF data from media files if the file upload is allowed. An attacker could create a specially crafted image file that, when processed by libexif, would cause the application to crash or, potentially expose data from the application\u0027s memory.
