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.
