"value": "OpenBSD Kernel Multicast Routing Uninitialized Memory Information Disclosure Vulnerability. This vulnerability allows local attackers to disclose sensitive information on affected installations of OpenBSD Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.\n\nThe specific flaw exists within the implementation of multicast routing. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute arbitrary code in the context of the kernel.\n. Was ZDI-CAN-14540."

"value": "Vulnerabilidad de divulgaci\u00f3n de informaci\u00f3n de memoria no inicializada de enrutamiento de multidifusi\u00f3n del kernel de OpenBSD. Esta vulnerabilidad permite a atacantes locales revelar informaci\u00f3n confidencial sobre las instalaciones afectadas de OpenBSD Kernel. Un atacante primero debe obtener la capacidad de ejecutar c\u00f3digo con pocos privilegios en el sistema de destino para poder explotar esta vulnerabilidad. La falla espec\u00edfica existe en la implementaci\u00f3n del enrutamiento de multidifusi\u00f3n. El problema se debe a la falta de una inicializaci\u00f3n adecuada de la memoria antes de acceder a ella. Un atacante puede aprovechar esto junto con otras vulnerabilidades para escalar privilegios y ejecutar c\u00f3digo arbitrario en el contexto del kernel. Era ZDI-CAN-14540."
