5 November 2024

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

Packages
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)

Update instructions
The problem can be corrected by updating your system to the following package versions:

Ubuntu 24.04
libopenjp2-7 - 2.5.0-2ubuntu0.2
libopenjpip7 - 2.5.0-2ubuntu0.2

In general, a standard system update will make all the necessary changes.
