CVE-2025-10925

A stack-based buffer overflow vulnerability exists in the ILBM file parsing functionality of GIMP. When processing a specially crafted ILBM image file, improper validation of user-supplied data length before copying to a stack buffer can lead to memory corruption. Successful exploitation allows an attacker to execute arbitrary code in the context of the current process. User interaction is required, as the victim must open a malicious ILBM file.

The vulnerability is classified as Important rather than Critical because it requires user interaction — exploitation cannot occur automatically. The attacker must convince a user to open a crafted file within GIMP, limiting the attack surface. Furthermore, the attack operates within the context of the current process, meaning system-level privileges are not directly obtained. However, due to the nature of stack-based buffer overflows, the issue is technically significant as it enables reliable code execution and full compromise of user data, making patching crucial.
