It was discovered that there was an integer overflow vulnerability in exiv2, a tool to manipulate images containing (eg.) EXIF metadata.

This could have resulted in a denial of service via a specially- crafted file.

For Debian 8 ‘Jessie’, this issue has been fixed in exiv2 version 0.24-4.1+deb8u4.

We recommend that you upgrade your exiv2 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
