CVE-2022-1122

A flaw was found in the opj2_decompress program in openjpeg2 2.4.0 in the way it handles an input directory with a large number of files. When it fails to allocate a buffer to store the filenames of the input directory, it calls free() on an uninitialized pointer, leading to a segmentation fault and a denial of service.

OpenJPEG is an open-source JPEG 2000 codec written in C language. It has been developed in order to promote the use of JPEG 2000, a still-image compression standard from the Joint Photographic Experts Group (JPEG). Since April 2015, it is officially recognized by ISO/IEC and ITU-T as a JPEG 2000 Reference Software.

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)
