Hi,

The following vulnerability was published for imagemagick.

CVE-2026-123273[0]:
| ImageMagick before 7.1.2-35 and 6.9.13-60 contains an infinite loop
| vulnerability in the SVG decoder because
| QueueAuthenticPixelCacheNexus in MagickCore/cache.c fails to
| validate requested region width and height. Attackers can supply a
| crafted SVG image that repeatedly requests a non-advancing pixel
| region, consuming CPU and hanging the decoding worker.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
