| Beschreibung: | Summary:
The remote host is missing an update for the Huawei EulerOS 'httpd' package(s) announced via the EulerOS-SA-2020-1359 advisory.
Vulnerability Insight:
In Apache HTTP Server 2.4 release 2.4.37 and prior, mod_session checks the session expiry time before decoding the session. This causes session expiry time to be ignored for mod_session_cookie sessions since the expiry time is loaded when the session is decoded.(CVE-2018-17199)
In Apache HTTP Server 2.4.18-2.4.39, using fuzzed network input, the http/2 session handling could be made to read memory after being freed, during connection shutdown.(CVE-2019-10082)
HTTP/2 (2.4.20 through 2.4.39) very early pushes, for example configured with 'H2PushResource', could lead to an overwrite of memory in the pushing request's pool, leading to crashes. The memory copied is that of the configured push link header values, not data supplied by the client.(CVE-2019-10081)
Some HTTP/2 implementations are vulnerable to unconstrained internal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint, however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both.(CVE-2019-9517)
In Apache HTTP Server 2.4.32-2.4.39, when mod_remoteip was configured to use a trusted intermediary proxy server using the 'PROXY' protocol, a specially crafted PROXY header could trigger a stack buffer overflow or NULL pointer deference. This vulnerability could only be triggered by a trusted proxy and not by untrusted HTTP clients.(CVE-2019-10097)
Affected Software/OS:
'httpd' package(s) on Huawei EulerOS Virtualization for ARM 64 3.0.6.0.
