Description Srikanth Balasubramanian 2026-07-03 16:32:46 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

ImageMagick before 7.1.2-22 contains an information disclosure vulnerability in the PasskeyEncipherImage method due to AES-CTR nonce reuse. Attackers can exploit nonce reuse in the cipher implementation to recover plaintext information from encrypted images.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
