"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2024:0116 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

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

    CVE-2023-45802:
    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 ofCVE-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.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
