CVE-2025-57807

Name of the Vulnerable Software and Affected Versions ImageMagick versions prior to 14.8.2

Description ImageMagick is free and open-source software used for editing and manipulating digital images. The software includes insecure functions: SeekBlob(), which allows advancing the stream offset beyond the current end without increasing capacity, and WriteBlob(), which expands by quantum + length instead of offset + length, and copies to data + offset. When offset is significantly larger than the extent, the copy targets memory beyond the allocation, resulting in a heap write on 64-bit builds. This does not require 2⁶⁴ arithmetic wrap, external delegates, or policy settings.

Recommendations Update to version 14.8.2 or later.
