Package : openjpeg2
Version : 2.1.0-2+deb8u8
CVE ID : CVE-2018-21010
Debian Bug : 939553
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.
