Hi,

The following vulnerability was published for imagemagick.

CVE-2025-66628[0]:
| ImageMagick is a software suite to create, edit, compose, or convert
| bitmap images. In versions 7.1.2-9 and prior, the TIM (PSX TIM)
| image parser contains a critical integer overflow vulnerability in
| its ReadTIMImage function (coders/tim.c). The code reads width and
| height (16-bit values) from the file header and calculates
| image_size = 2 * width * height without checking for overflow. On
| 32-bit systems (or where size_t is 32-bit), this calculation can
| overflow if width and height are large (e.g., 65535), wrapping
| around to a small value. This results in a small heap allocation via
| AcquireQuantumMemory and later operations relying on the dimensions
| can trigger an out of bounds read. This issue is fixed in version
| 7.1.2-10.


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