Original advisory details:

 Alex Nichols and Jakob Hirsch discovered that the Apache HTTP Server
 mod_authnz_ldap module incorrectly handled missing charset encoding
 headers. A remote attacker could possibly use this issue to cause the
 server to crash, resulting in a denial of service. (CVE-2017-15710)

 Elar Lang discovered that the Apache HTTP Server incorrectly handled
 certain characters specified in <FilesMatch>. A remote attacker could
 possibly use this issue to upload certain files, contrary to expectations.
 (CVE-2017-15715)

 It was discovered that the Apache HTTP Server mod_session module
 incorrectly handled certain headers. A remote attacker could possibly use
 this issue to influence session data. (CVE-2018-1283)

 Robert Swiecki discovered that the Apache HTTP Server incorrectly handled
 certain requests. A remote attacker could possibly use this issue to cause
 the server to crash, leading to a denial of service. (CVE-2018-1301)

 Robert Swiecki discovered that the Apache HTTP Server mod_cache_socache
 module incorrectly handled certain headers. A remote attacker could
 possibly use this issue to cause the server to crash, leading to a denial
 of service. (CVE-2018-1303)

 Nicolas Daniels discovered that the Apache HTTP Server incorrectly
 generated the nonce when creating HTTP Digest authentication challenges.
 A remote attacker could possibly use this issue to replay HTTP requests
 across a cluster of servers. (CVE-2018-1312)");
