Summary
httpd security update
Details

Apache HTTP Server is a powerful and flexible HTTP/1.1 compliant web server.

Security Fix(es):

In Apache HTTP Server versions 2.4.0 to 2.4.46 a specially crafted SessionHeader sent by an origin server could cause a heap overflow(CVE-2021-26691)

Apache HTTP Server versions 2.4.41 to 2.4.46 modproxyhttp can be made to crash (NULL pointer dereference) with specially crafted requests using both Content-Length and Transfer-Encoding headers, leading to a Denial of Service(CVE-2020-13950)

Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in modauthdigest. 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(CVE-2020-35452)

Apache HTTP Server versions 2.4.39 to 2.4.46 Unexpected matching behavior with MergeSlashes OFF(CVE-2021-30641)
