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.
