CVE-2023-34304

Estado: AnalizadaAlta (7.8)—

Ashlar-Vellum Cobalt Out-Of-Bounds Access Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ashlar-Vellum Cobalt. 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 IGS files. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. . Was ZDI-CAN-18006.

Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario en las instalaciones afectadas de Ashlar-Vellum Cobalt. Se requiere la interacción del usuario para aprovechar esta vulnerabilidad, ya que el objetivo debe visitar una página maliciosa o abrir un archivo malicioso. La falla específica existe en el análisis de archivos IGS. El problema se debe a la falta de una validación adecuada de los datos proporcionados por el usuario, lo que puede provocar un acceso a la memoria más allá del final de un búfer asignado.
