CVE-2026-62439: Gimp: gimp: file-pvr plug-in pvr file parsing integer overflow heap-based buffer overflow vulnerability

Description

A flaw was found in GIMP. An integer overflow occurs in the file-pvr plug-in when calculating memory buffer sizes for image dimensions. By tricking a user into opening or previewing a specially crafted PowerVR (.pvr) file, an attacker can trigger a heap-based buffer overflow, potentially leading to arbitrary code execution or a Denial of Service (DoS) via an application crash.
