Code execution via wrapped ANI metadata allocation
Published Apr 11, 2026 · Updated Apr 11, 2026
Integer overflow in GIMP 3.0.8 ANI parsing allows remote attackers to execute code by convincing a user to open a crafted file. The file-ico plug-in's ani_load_image function adds one to attacker-controlled 32-bit Name or Artist metadata sizes, wraps the allocation length, and reads the declared data into the undersized buffer. Exploitation requires user interaction and runs code with the privileges of the GIMP process.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
