Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Cookie header handled by mod_session can cause a NULL pointer dereference and crash, leading to a possible Denial Of Service
A NULL pointer dereference was found in Apache httpd mod_session. The highest threat from this vulnerability is to system availability.
Отчет
This is a null pointer deference caused when using mod_session. It can result in crash of httpd child process by a remote attacker.
Меры по смягчению последствий
Only configurations which use the "SessionEnv" directive (which is not widely used) are vulnerable to this flaw. SessionEnv is not enabled in default configuration of httpd package shipped with Red Hat Products.
