Node.js before 16.4.1, 14.17.2, 12.22.2 is vulnerable to an out-of-bounds read when uv__idna_toascii() is used to convert strings to ASCII. The pointer p is read and increased without checking whether it is beyond pe, with the latter holding a pointer to the end of the buffer. This can lead to information disclosures or crashes. This function can be triggered via uv_getaddrinfo().

This function can be triggered via uv_getaddrinfo().
Node.js versiones anteriores a 16.4.1, 14.17.2, 12.22.2, es vulnerable a una lectura fuera de límites cuando la función uv__idna_toascii() es usada para convertir cadenas a ASCII. El puntero p es leído e incrementado sin comprobar si está más allá de pe, siendo este último un puntero al final del buffer. Esto puede conllevar a una revelación de información o el bloqueo de la misma. Esta función puede ser desencadenada por medio de la función uv_getaddrinfo()
