Descriptions

In Netwide Assembler (NASM) 2.14rc0, there are multiple heap use after free vulnerabilities in the tool nasm. The related heap is allocated in the token() function and freed in the detoken() function (called by pp_getline()) - it is used again at multiple positions later that could cause multiple damages. For example, it causes a corrupted double-linked list in detoken(), a double free or corruption in delete_Token(), and an out-of-bounds write in detoken(). It has a high possibility to lead to a remote code execution attack.

En Netwide Assembler (NASM) versión 2.14rc0, existen múltiples vulnerabilidades de acceso a la región heap de la memoria previamente liberada en la herramienta nasm. La región heap relacionada es asignada en la función token() y se libera en la función detoken() (llamada por pp_getline()); se usa de nuevo en varias posiciones más adelante, lo que podría causar daños múltiples. Por ejemplo, provoca una lista de doble enlace dañada en detoken(), una doble liberación o corrupción en delete_Token() y una escritura fuera de límites en detoken(). Tiene una alta posibilidad de provocar un ataque de ejecución de código remota.
