Several security issues were fixed in OpenJPEG.

Releases
Ubuntu 24.10 Ubuntu 24.04 LTS Ubuntu 22.04 LTS Ubuntu 20.04 LTS Ubuntu 18.04 ESM Ubuntu 16.04 ESM

Details
It was discovered that OpenJPEG incorrectly handled certain memory
operations when using the command line ”-ImgDir” in a directory with a
large number of files, leading to an integer overflow vulnerability. An
attacker could potentially use this issue to cause a denial of service.
This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS,
Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2021-29338)

It was discovered that OpenJPEG incorrectly handled decompressing certain
.j2k files in sycc420_to_rgb, leading to a heap-based buffer overflow
vulnerability. If a user or automated system were tricked into opening
a specially crafted file, an attacker could possibly use this issue to
execute arbitrary code. (CVE-2021-3575)

It was discovered that OpenJPEG incorrectly handled certain memory
operations in the opj2_decompress program. An attacker could potentially
use this issue to cause a denial of service. This issue only affected
Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS and Ubuntu 22.04 LTS.
(CVE-2022-1122)

Ubuntu 24.04
libopenjp2-7 - 2.5.0-2ubuntu0.2
