Details

As written in the advisory (Markdown source, shown as plain text).

### Description A heap information disclosure vulnerability exists in ImageMagick's PSD (Adobe Photoshop) format handler. When processing a maliciously crafted PSD file containing ZIP-compressed layer data that decompresses to less than the expected size, uninitialized heap memory is leaked into the output image. ### Expected Impact Information disclosure leading to potential exposure of sensitive data from server memory.
