Package        : openjpeg2
Version        : 2.1.0-2+deb8u7
CVE ID         : CVE-2016-9112 CVE-2018-20847
Debian Bug     : 931294 844551

Two security vulnerabilities were discovered in openjpeg2, a JPEG 2000
image library.

CVE-2016-9112

     A floating point exception or divide by zero in the function
     opj_pi_next_cprl may lead to a denial-of-service.

CVE-2018-20847

     An improper computation of values in the function
     opj_get_encoding_parameters can lead to an integer overflow.
     This issue was partly fixed by the patch for CVE-2015-1239.

For Debian 8 "Jessie", these problems have been fixed in version
2.1.0-2+deb8u7.

We recommend that you upgrade your openjpeg2 packages.
