Descriptions

In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_ssl may dereference a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port.

En Apache httpd, en versiones 2.2.x anteriores a la 2.2.33 y versiones 2.4.x anteriores a la 2.4.26, mod_ssl podría desreferenciar un puntero NULL cuando los módulos de terceros llaman a ap_hook_process_connection() durante una petición HTTP a un puerto HTPS.

A NULL pointer dereference flaw was found in the httpd's mod_ssl module. A remote attacker could use this flaw to cause an httpd child process to crash if another module used by httpd called a certain API function during the processing of an HTTPS request.
