"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2023:0144 advisory.

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

    CVE-2006-20001:
    A carefully crafted If: request header can cause a memory read, or write of a single zero byte, in a pool
    (heap) memory location beyond the header value sent. This could cause the process to crash. This issue
    affects Apache HTTP Server 2.4.54 and earlier.

    CVE-2022-22719:
    A carefully crafted request body can cause a read to a random memory area which could cause the process to
    crash. This issue affects Apache HTTP Server 2.4.52 and earlier.

    CVE-2022-22721:
    If LimitXMLRequestBody is set to allow request bodies larger than 350MB (defaults to 1M) on 32 bit systems
    an integer overflow happens which later causes out of bounds writes. This issue affects Apache HTTP Server
    2.4.52 and earlier.

    CVE-2022-23943:
    Out-of-bounds Write vulnerability in mod_sed of Apache HTTP Server allows an attacker to overwrite heap
    memory with possibly attacker provided data. This issue affects Apache HTTP Server 2.4 version 2.4.52 and
    prior versions.

    CVE-2022-26377:
    Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of
    Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This
    issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.53 and prior versions.

    CVE-2022-28614:
    The ap_rwrite() function in Apache HTTP Server 2.4.53 and earlier may read unintended memory if an
    attacker can cause the server to reflect very large input using ap_rwrite() or ap_rputs(), such as with
    mod_luas r:puts() function. Modules compiled and distributed separately from Apache HTTP Server that use
    the 'ap_rputs' function and may pass it a very large (INT_MAX or larger) string must be compiled against
    current headers to resolve the issue.

    CVE-2022-29404:
    In Apache HTTP Server 2.4.53 and earlier, a malicious request to a lua script that calls r:parsebody(0)
    may cause a denial of service due to no default limit on possible input size.

    CVE-2022-30556:
    Apache HTTP Server 2.4.53 and earlier may return lengths to applications calling r:wsread() that point
    past the end of the storage allocated for the buffer.

    CVE-2022-31813:
    Apache HTTP Server 2.4.53 and earlier may not send the X-Forwarded-* headers to the origin server based on
    client side Connection header hop-by-hop mechanism. This may be used to bypass IP based authentication on
    the origin server/application.

    CVE-2022-28615:
    Apache HTTP Server 2.4.53 and earlier may crash or disclose information due to a read beyond bounds in
    ap_strcmp_match() when provided with an extremely large input buffer. While no code distributed with the
    server can be coerced into such a call, third-party modules or lua scripts that use ap_strcmp_match() may
    hypothetically be affected.

    CVE-2022-30522:
    If Apache HTTP Server 2.4.53 is configured to do transformations with mod_sed in contexts where the input
    to mod_sed may be very large, mod_sed may make excessively large memory allocations and trigger an abort.

    CVE-2022-36760:
    Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of
    Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to.  This
    issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.54 and prior versions.

    CVE-2022-37436:
    Prior to Apache HTTP Server 2.4.55, a malicious backend can cause the response headers to be truncated
    early, resulting in some headers being incorporated into the response body. If the later headers have any
    security purpose, they will not be interpreted by the client.

    CVE-2023-25690:
    Some mod_proxy configurations on Apache HTTP Server versions 2.4.0 through 2.4.55 allow a HTTP Request
    Smuggling attack.
    Configurations are affected when mod_proxy is enabled along with some form of RewriteRule
    or ProxyPassMatch in which a non-specific pattern matches
    some portion of the user-supplied request-target (URL) data and is then
    re-inserted into the proxied request-target using variable
    substitution. For example, something like:
    RewriteEngine on
    RewriteRule ^/here/(.*) http://example.com:8080/elsewhere?$1; [P]
    ProxyPassReverse /here/ http://example.com:8080/
    Request splitting/smuggling could result in bypass of access controls in the proxy server, proxying
    unintended URLs to existing origin servers, and cache poisoning. Users are recommended to update to at
    least version 2.4.56 of Apache HTTP Server.
