CVE-2026-2049
GIMP HDR File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability
Description
GIMP HDR File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of HDR files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28618.

Action Type Old Value New Value Added Translation Title: GIMP, Description: Vulnerabilidad de ejecución remota de código por desbordamiento de búfer basado en montículo en el análisis de archivos HDR de GIMP. Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario en instalaciones afectadas de GIMP. Se requiere interacción del usuario para explotar esta vulnerabilidad, ya que el objetivo debe visitar una página maliciosa o abrir un archivo malicioso. La falla específica existe dentro del análisis de archivos HDR. El problema resulta de la falta de validación adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos a un búfer basado en montículo. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual. Fue ZDI-CAN-28618. -
