Description OSIDB Bzimport 2026-06-10 23:01:57 UTC

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-48 and 7.1.2-24, a missing check in the DCM decoder could result in an image with invalid dimensions and that could cause crashes in other operation. This issue has been patched in versions 6.9.13-48 and 7.1.2-24.
