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.
