CVE-2018-19935
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.28%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
