Hi,

The following vulnerability was published for gimp.

CVE-2026-96545[0]:
| An out-of-bounds heap read flaw was found in GIMP's TIM image
| loader. When a user opens a crafted 4bpp TIM image that causes
| promotion to an RGBA layer, the file-tim plug-in allocates an
| undersized row buffer but processes it using the larger RGBA row
| size. This can copy adjacent heap contents into the decoded image
| and may crash the plug-in.


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