When processing a SUBSCRIBE request, the res_pjsip_pubsub module stores the accepted formats present in the Accept headers of the request. This code did not limit the number of headers it processed, despite having a fixed limit of 32. If more than 32 Accept headers were present, the code would write outside of its memory and cause a crash."

Al procesar una petici\u00f3n SUBSCRIBE, el m\u00f3dulo res_pjsip_pubsub almacena los formatos aceptados presentes en las cabeceras Accept de la petici\u00f3n. Este c\u00f3digo no limitaba el n\u00famero de cabeceras que procesaba, a pesar de tener un l\u00edmite fijado en 32. Si estuviesen presentes m\u00e1s de 32 cabeceras Accept, el c\u00f3digo escribir\u00eda fuera de la memoria y provocar\u00eda un cierre inesperado."
