Hi, The following vulnerability was published for imagemagick. CVE-2025-57807[0]: | ImageMagick is free and open-source software used for editing and | manipulating digital images. ImageMagick versions lower than 14.8.2 | include insecure functions: SeekBlob(), which permits advancing the | stream offset beyond the current end without increasing capacity, | and WriteBlob(), which then expands by quantum + length (amortized) | instead of offset + length, and copies to data + offset. When offset | ≫ extent, the copy targets memory beyond the allocation, producing a | deterministic heap write on 64-bit builds. No 2⁶⁴ arithmetic wrap, | external delegates, or policy settings are required. This is fixed | in version 14.8.2. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
