CVE-2022-1122: Debian Linux

Medium severity, CVSS 5.5. EPSS: 1.1% chance of exploitation in the next 30 days.

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.

Affected products

• Debian Debian Linux: version 9.0 only
• Fedoraproject Fedora: version 34 only; version 35 only; version 36 only
• Uclouvain Openjpeg: version 2.4.0 only
