The Apache httpd project reports:

important: Read after free in mod_http2 (CVE-2017-9789)
When under stress, closing many connections, the HTTP/2 handling code would sometimes access memory after it has been freed, resulting in potentially erratic behaviour.

important: Uninitialized memory reflection in mod_auth_digest (CVE-2017-9788)
The value placeholder in [Proxy-]Authorization headers of type 'Digest' was not initialized or reset before or between successive key=value assignments. by mod_auth_digest.
Providing an initial key with no '=' assignment could reflect the stale value of uninitialized pool memory used by the prior request, leading to leakage of potentially confidential information, and a segfault.
