"According to the versions of the httpd packages installed, the EulerOS Virtualization installation on the remote host is
affected by the following vulnerabilities :

  - Out-of-bounds Read vulnerability in mod_macro of Apache HTTP Server.This issue affects Apache HTTP Server:
    through 2.4.57. (CVE-2023-31122)

  - When a HTTP/2 stream was reset (RST frame) by a client, there was a time window were the request's memory
    resources were not reclaimed immediately. Instead, de-allocation was deferred to connection close. A
    client could send new requests and resets, keeping the connection busy and open and causing the memory
    footprint to keep on growing. On connection close, all resources were reclaimed, but the process might run
    out of memory before that. This was found by the reporter during testing of CVE-2023-44487 (HTTP/2 Rapid
    Reset Exploit) with their own test client. During 'normal' HTTP/2 use, the probability to hit this bug is
    very low. The kept memory would not become noticeable before the connection closes or times out. Users are
    recommended to upgrade to version 2.4.58, which fixes the issue. (CVE-2023-45802)

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.");
