Hi,

The following vulnerability was published for gimp.

CVE-2026-82343[0]:
| A flaw was found in the file-psd plugin in GIMP. When processing a
| specially crafted PSD image file, the plugin does not properly
| validate the channel-count parameter. This incorrect validation
| leads to improper memory bounds checking, resulting in both a heap
| out-of-bounds read and a stack out-of-bounds access. This issue can
| result in an application crash, leading to a denial of service or a
| limited information disclosure of memory contents.


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