openjpeg2 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 24.10
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in OpenJPEG.

Software Description:
- openjpeg2: JPEG 2000 image compression/decompression library

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)
