# CVE-2026-79902: Gimp: stack vla size underflow denial of service in seattle

Status: published. Published: 2026-08-26. Updated: 2026-11-06.

A flaw was found in the Seattle FilmWorks plugin in GIMP. When processing a specially crafted SFW image file, the plugin allocates a Variable-Length Array (VLA) on the stack without integer overflow checks, causing an unbounded stack allocation. This issue leads to an application crash, resulting in a denial of service.

## Remediation

- workaround: To mitigate this vulnerability, do not open SFW files from untrusted sources with GIMP. (source: CNA: redhat)
