Hi, The following vulnerability was published for gimp. CVE-2026-92248[0]: | A flaw was found in the file-psd plugin in GIMP. When generating a | thumbnail preview for a specially crafted PSD (Photoshop Document) | image file, an integer overflow occurs during the multiplication of | values from an embedded JPEG header. This leads to an undersized | heap allocation, resulting in a heap-based buffer overflow when the | image data is decoded. This buffer overflow corrupts adjacent heap | objects, allowing for a controlled memory write that can result in | an application crash or arbitrary code execution. https://gitlab.gnome.org/GNOME/gimp/-/work_items/16775 https://gitlab.gnome.org/GNOME/gimp/-/merge_requests/3009 https://gitlab.gnome.org/GNOME/gimp/-/commit/6b1e668699ebebc35152ad6c3db4b445cd78b7df If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
