A crafted .mo file may lead the buffer size calculation to overflow, leading to out-of-bound reads and writes. This flaw allows an attacker to leak sensitive data or overwrite critical data, possibly circumventing secure boot protections."

A manipulado .MO El archivo puede llevar el c\u00e1lculo del tama\u00f1o del b\u00fafer a desbordarse, lo que lleva a lecturas y escrituras fuera de los l\u00edmite.
