CVE-2023-34301

Vulnerabilidad de ejecución remota de código de desreferencia de puntero no confiable en el análisis de archivos Ashlar-Vellum Cobalt CO. 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 CO. El problema se debe a la falta de validación adecuada de un valor proporcionado por el usuario antes de eliminar la referencia a él como puntero. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual. Era ZDI-CAN-17909.

Ashlar-Vellum Cobalt CO File Parsing Untrusted Pointer Dereference 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 CO files. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to execute code in the context of the current process.
