The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to usage of the ap_get_basic_auth_pw() function by third-party modules outside of the authentication phase. A remote attacker can create a specially crafted HTTP request to vulnerable web server, bypass authentication requirements and gain unauthorized access to otherwise protected information.

The vulnerability allows a remote attacker to perform denial of service attack.
The vulnerability exists due to a NULL pointer dereference error within mod_ssl module, when third-party modules call ap_hook_process_connection() function during an HTTP request to an HTTPS port. A remote attacker can send a specially crafted HTTP request and crash the affected web server.

The vulnerability allows a remote attacker to obtain potentially sensitive information.
The vulnerability exists due to use-after-free error when processing HTTP OPTIONS requests in server/core.c, when limits are configured in .htaccess or httpd.conf configuration files. A remote unauthenticated attacker can read portions of memory through HTTP OPTIONS requests and gain access to potentially sensitive data.
The vulnerability is dubbed Optionsbleed.

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The weakness exists due to an out-of-bounds array dereference in the apr_time_exp_get() function. A remote attacker can access prior out-of-bounds memory, reveal the contents of a different static heap value and read arbitrary files or cause the application to crash.
