CVE-2020-24753

A memory corruption vulnerability in Objective Open CBOR Run-time (oocborrt) in versions before 2020-08-12 could allow an attacker to execute code via crafted Concise Binary Object Representation (CBOR) input to the cbor2json decoder. An uncaught error while decoding CBOR Major Type 3 text strings leads to the use of an attacker-controllable uninitialized stack value. This can be used to modify memory, causing a crash or potentially exploitable heap corruption.

Una vulnerabilidad de corrupción de la memoria en Objective Open CBOR Run-time (oocborrt) en versiones anteriores al 12-08-2020, podría permitir a un atacante ejecutar código por medio de la entrada de Concise Binary Object Representation (CBOR) hacia el decodificador cbor2json. Un error no detectado al decodificar cadenas de texto CBOR Major Type 3 conlleva al uso de un valor de pila no inicializado controlable por el atacante. Esto puede ser usado para modificar la memoria, causando un bloqueo o una corrupción de la pila potencialmente explotable
