Beschreibung:	Summary: The remote host is missing an update for the 'apache' package(s) announced via the MGASA-2021-0265 advisory. Vulnerability Insight: mod_proxy_wstunnel tunneling of non Upgraded connections: Apache HTTP Server versions 2.4.6 to 2.4.46 mod_proxy_wstunnel configured on an URL that is not necessarily Upgraded by the origin server was tunneling the whole connection regardless, thus allowing for subsequent requests on the same connection to pass through with no HTTP validation, authentication or authorization possibly configured. (CVE-2019-17567). mod_proxy_http NULL pointer dereference: Apache HTTP Server versions 2.4.41 to 2.4.46 mod_proxy_http 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). mod_auth_digest possible stack overflow by one nul byte: 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 (CVE-2020-35452). mod_session NULL pointer dereference: Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Cookie header handled by mod_session can cause a NULL pointer dereference and crash, leading to a possible Denial Of Service (CVE-2021-26690). mod_session response handling heap overflow: 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). Unexpected URL matching with 'MergeSlashes OFF': Apache HTTP Server versions 2.4.39 to 2.4.46 Unexpected matching behavior with 'MergeSlashes OFF'(CVE-2021-30641). NULL pointer dereference on specially crafted HTTP/2 request: Apache HTTP Server protocol handler for the HTTP/2 protocol checks received request headers against the size limitations as configured for the server and used for the HTTP/1 protocol as well. On violation of these restrictions and HTTP response is sent to the client with a status code indicating why the request was rejected. This rejection response was not fully initialised in the HTTP/2 protocol handler if the offending header was the very first one received or appeared in a footer. This led to a NULL pointer dereference on initialised memory, crashing reliably the child process. Since such a triggering HTTP/2 request is easy to craft and submit, this can be exploited to DoS the server. This issue affected mod_http2 1.15.17 and Apache HTTP Server version 2.4.47 only. Apache HTTP Server 2.4.47 was never released. (CVE-2021-31618). Affected Software/OS: 'apache' package(s) on Mageia 7, Mageia 8. Solution: Please install the updated package(s).
