CVE-2020-35452:
Apache HTTP Server versions 2.4.0 to 2.4.46 A specially
crafted Digest nonce can cause a stack overflow in
mod_auth_digest. There is no report of this overflow
being exploitable, nor the Apache HTTP Server team could
create one, though some particular compiler and/or
compilation option might make it possible, with limited
consequences anyway due to the size (a single byte) and
the value (zero byte) of the overflow
