"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.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
