Details: https://nvd.nist.gov/vuln/detail/CVE-2025-55212

Backport the patch that is mentioned in the NVD advisory.

Notes about the backport:
The original patch deletes two extra lines compared to the backport:
those lines were a previous attempt[1] to solve the same vulnerability,
and the final patch reverted them. Since that patch wasn't part of the
recipe, those deletions were dropped from the backported patch.

The PerceptibleReciprocal function was renamed[2] to MagickSafeReciprocal
after the recipe's revision, but there were no functional changes
in the function's behavior.
