Doc Text:
A flaw was found in ImageMagick. A remote attacker could exploit a heap-use-after-free (UAF) vulnerability by providing a specially crafted MSL script. This vulnerability occurs when the operation element handler replaces and frees an image while the parser continues to read from it. Successful exploitation could lead to a denial of service.

Description OSIDB Bzimport 2026-02-24 02:02:23 UTC 
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a crafted MSL script triggers a heap-use-after-free. The operation element handler replaces and frees the image while the parser continues reading from it, leading to a UAF in ReadBlobString during further parsing. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
