Descriptions

In PHP versions 7.3.x below 7.3.13 and 7.4.0 on Windows, when supplying custom headers to mail() function, due to mistake introduced in commit 78f4b4a2dcf92ddbccea1bb95f8390a18ac3342e, if the header is supplied in lowercase, this can result in double-freeing certain memory locations.

En PHP versiones 7.3.x por debajo de 7.3.13 y 7.4.0 en Windows, al suministrar encabezados personalizados para la función mail(), debido a un error introducido en el commit 78f4b4a2dcf92ddbccea1bb95f8390a18ac3342e, si el encabezado se suministra en minúsculas, esto puede resultar en una doble liberación de ciertas ubicaciones de memoria.
