Descriptions

ext/imap/php_imap.c in PHP 5.x and 7.x before 7.3.0 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an empty string in the message argument to the imap_mail function.

ext/imap/php_imap.c en PHP 5.x y 7.x anteriores a la 7.3.0 permite que atacantes remotos provoquen una denegación de servicio (desreferencia de puntero NULL y cierre inesperado de la aplicación) mediante una cadena vacía en el argumento del mensaje en la función imap_mail.

Multiple security issues were found in PHP, a widely-used open source denial of service/information disclosure when parsing malformed images, the Apache module allowed cross-site-scripting via the body of a insufficient input validation which can result in the execution of arbitrary shell commands in the imap_open() function and denial of service in the imap_mail() function.
