an out-of-bounds write vulnerability due to an integer overflow was reported in libexif, a library to parse exif files. This flaw might be leveraged by remote attackers to cause denial of service, or potentially execute arbitrary code via crafted image files.

For Debian 8 Jessie, this problem has been fixed in version 0.6.21-2+deb8u1.

We recommend that you upgrade your libexif packages.
