Descriptions

In YARA 3.8.1, bytecode in a specially crafted compiled rule can read uninitialized data from VM scratch memory in libyara/exec.c. This can allow attackers to discover addresses in the real stack (not the YARA virtual stack).

En YARA 3.8.1, el código de bytes en una regla compilada especialmente manipulada puede leer datos no inicializados de la memoria temporal de la máquina virtual en libyara/exec.c. Esto puede permitir que los atacantes descubran direcciones en la pila real (no en la pila virtual de YARA).
