openjpeg2 - security update

Multiple vulnerabilities in OpenJPEG, a JPEG 2000 image compression /
decompression library, may result in denial of service or the execution
of arbitrary code if a malformed JPEG 2000 file is processed.

For the stable distribution (jessie), these problems have been fixed in
version 2.1.0-2+deb8u1.

We recommend that you upgrade your openjpeg2 packages.
