		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">Apache HTTP Server is a powerful and flexible HTTP/1.1 compliant web server.

Security Fix(es):

A carefully crafted request uri-path can cause mod_proxy_uwsgi to read above the allocated memory and crash (DoS). This issue affects Apache HTTP Server versions 2.4.30 to 2.4.48 (inclusive).(CVE-2021-36160)

Malformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP Server 2.4.48 and earlier.(CVE-2021-34798)

A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier.(CVE-2021-40438)</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for httpd is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2.

openEuler Security has rated this update as having a security impact of critical. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.</Note>
