No patch is currently available for affected versions.

Medium severity vulnerability in ImageMagick. A heap out-of-bounds read vulnerability exists in the `coders/dcm.c` module. When processing DICOM files with a specific configuration, the decoder loop incorrectly reads bytes per iteration. This causes the function to read past the end of the allocated buffer, potentially leading to a Denial of Service (crash) or Information Disclosure (leaking heap memory into the image).

ImageMagick versions prior to 7.1.2-15 and 6.9.13-40 allow local attackers to bypass the secure policy's stdin/stdout restrictions by using fd:<n> pseudo-filenames (e.g., fd:0, fd:1), enabling unauthorized reading and writing to standard streams. This vulnerability affects systems relying on ImageMagick's default security policies to prevent stream manipulation. No patch is currently available, though administrators can manually update their security policy configuration as a workaround.

ImageMagick before versions 7.1.2-15 and 6.9.13-40 allows local attackers to bypass path security policies and disclose sensitive files through path traversal sequences in filenames, as the policy enforcement occurs before filesystem resolution normalizes the paths.
