Affected Packages:
Security database references:
In the Debian bugtracking system: Bug 939553.
In Mitre's CVE dictionary: CVE-2018-21010.
More information:

A heap buffer overflow vulnerability was discovered in openjpeg2, the open-source JPEG 2000 codec. This vulnerability is caused by insufficient validation of width and height of image components in color_apply_icc_profile (src/bin/common/color.c).

Remote attackers might leverage this vulnerability via a crafted JP2 file, leading to denial of service (application crash) or any other undefined behavior.

For Debian 8 Jessie, this problem has been fixed in version 2.1.0-2+deb8u8.

We recommend that you upgrade your openjpeg2 packages.
