Package        : openjpeg2
Version        : 2.1.0-2+deb8u5
CVE ID         : CVE-2017-17480 CVE-2018-18088

Multiple vulnerabilities have been discovered in openjpeg2, the
open-source JPEG 2000 codec.

CVE-2017-17480

  Write stack buffer overflow due to missing buffer length formatter in
  fscanf call (jp3d and jpwl codecs). This vulnerability might be
  leveraged by remote attackers using crafted jp3d and jpwl files to
  cause denial of service or possibly remote code execution.

CVE-2018-18088

  Null pointer dereference caused by null image components in imagetopnm.
  This vulnerability might be leveraged by remote attackers using crafted
  BMP files to cause denial of service.

For Debian 8 "Jessie", these problems have been fixed in version
2.1.0-2+deb8u5.

We recommend that you upgrade your openjpeg2 packages.
