Several security issues were fixed in Apache HTTP Server.

It was discovered that the Apache HTTP Server mod_dav module incorrectly
handled certain If: request headers. A remote attacker could possibly use
this issue to cause the server to crash, resulting in a denial of service.

incorrectly interpreted certain HTTP Requests. A remote attacker could
possibly use this issue to perform an HTTP Request Smuggling attack.
