"The exiv2 library is vulnerable to multiple issues that can all lead
to denial of service of the applications relying on the library to
parse images' metadata.

CVE-2017-11591

Denial of service via floating point exception in the Exiv2::ValueType
function.

CVE-2017-11683

Denial of service through failing assertion triggered by crafted
image.

CVE-2017-14859 / CVE-2017-14862 / CVE-2017-14864

Denial of service through invalid memory access triggered by a crafted
image.

For Debian 7 'Wheezy', these problems have been fixed in version
0.23-1+deb7u2.

We recommend that you upgrade your exiv2 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."
