This can lead to out-of-bounds read of global memory, potentially causing a crash or information disclosure or crash. Affected functions include mb_convert_encoding(), mb_detect_encoding(), mb_convert_variables(), and mb_detect_order(), as well as the mbstring.detect_order and mbstring.http_output INI settings."},{"lang":"es","value":"En versiones de PHP 8.4.* anteriores a 8.4.21 y 8.5.* anteriores a 8.5.6, cuando un nombre de codificación que contiene un byte NUL incrustado se pasa a mb_convert_encoding() o funciones mbstring relacionadas, el código asume incorrectamente que cuando strncasecmp() devuelve 0 significa que las cadenas tienen la misma longitud. Esto puede llevar a una lectura fuera de límites de la memoria global, lo que podría causar un fallo o revelación de información o un fallo.
