A bug exists in the way mod_ssl handled client renegotiations. A remote
attacker could send a carefully crafted request that would cause mod_ssl to
enter a loop leading to a denial of service. This bug can be only triggered
with Apache HTTP Server version 2.4.37 when using OpenSSL version 1.1.1 or
later, due to an interaction in changes to handling of renegotiation
attempts.
