EulerOS Virtualization 2.9.1 : httpd (EulerOS-SA-2021-1602)
critical Nessus Plugin ID 147602
Synopsis
The remote EulerOS Virtualization host is missing multiple security updates.Description
According to the versions of the httpd packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :- Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above 'info' will mitigate this vulnerability for unpatched servers.(CVE-2020-11993)
- Apache HTTP server 2.4.32 to 2.4.44 mod_proxy_uwsgi info disclosure and possible RCE(CVE-2020-11984)
- Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via 'H2Push off' will mitigate this vulnerability for unpatched servers.(CVE-2020-9490)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
