"The version of AOS installed on the remote host is prior to 6.8.0.5. It is, therefore, affected by multiple
vulnerabilities as referenced in the NXSA-AOS-6.8.0.5 advisory.

  - An information disclosure vulnerability exists in curl <v8.1.0 when doing HTTP(S) transfers, libcurl might
    erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send, even when the
    `CURLOPT_POSTFIELDS` option has been set, if the same handle previously wasused to issue a `PUT` request
    which used that callback. This flaw may surprise the application and cause it to misbehave and either send
    off the wrong data or use memory after free or similar in the second transfer. The problem exists in the
    logic for a reused handle when it is (expected to be) changed from a PUT to a POST. (CVE-2023-28322)

  - This flaw allows an attacker to insert cookies at will into a running program using libcurl, if the
    specific series of conditions are met. libcurl performs transfers. In its API, an application creates
    easy handles that are the individual handles for single transfers. libcurl provides a function call that
    duplicates en easy handle called
    [curl_easy_duphandle](https://curl.se/libcurl/c/curl_easy_duphandle.html). If a transfer has cookies
    enabled when the handle is duplicated, the cookie-enable state is also cloned - but without cloning the
    actual cookies. If the source handle did not read any cookies from a specific file on disk, the cloned
    version of the handle would instead store the file name as `none` (using the four ASCII letters, no
    quotes). Subsequent use of the cloned handle that does not explicitly set a source to load cookies from
    would then inadvertently load cookies from a file named `none` - if such a file exists and is readable in
    the current directory of the program using libcurl. And if using the correct file format of course.
    (CVE-2023-38546)

  - CVE-2023-38546 is a cookie injection vulnerability in the curl_easy_duphandle(), a function in libcurl
    that duplicates easy handles.  When duplicating an easy handle, if cookies are enabled, the duplicated
    easy handle will not duplicate the cookies themselves, but would instead set the filename to none.'
    Therefore, when the duplicated easy handle is subsequently used, if a source was not set for the cookies,
    libcurl would attempt to load them from the file named none' on the disk.  This vulnerability is rated
    low, as the various conditions required for exploitation are unlikely.  (CVE-2023-38546)

  - This flaw allows a malicious HTTP server to set super cookies in curl that are then passed back to more
    origins than what is otherwise allowed or possible. This allows a site to set cookies that then would get
    sent to different and unrelated sites and domains. It could do this by exploiting a mixed case flaw in
    curl's function that verifies a given cookie domain against the Public Suffix List (PSL). For example a
    cookie could be set with `domain=co.UK` when the URL used a lower case hostname `curl.co.uk`, even though
    `co.uk` is listed as a PSL domain. (CVE-2023-46218)

  - libexpat through 2.5.0 allows a denial of service (resource consumption) because many full reparsings are
    required in the case of a large token for which multiple buffer fills are needed. (CVE-2023-52425)

  - This flaw makes curl overflow a heap based buffer in the SOCKS5 proxy handshake. When curl is asked to
    pass along the host name to the SOCKS5 proxy to allow that to resolve the address instead of it getting
    done by curl itself, the maximum length that host name can be is 255 bytes. If the host name is detected
    to be longer, curl switches to local name resolving and instead passes on the resolved address only. Due
    to this bug, the local variable that means let the host resolve the name could get the wrong value
    during a slow SOCKS5 handshake, and contrary to the intention, copy the too long host name to the target
    buffer instead of copying just the resolved address there. The target buffer being a heap based buffer,
    and the host name coming from the URL that curl has been told to operate with. (CVE-2023-38545)

  - CVE-2023-38545 is a heap-based buffer overflow vulnerability in the SOCKS5 proxy handshake in libcurl and
    curl.  When curl is given a hostname to pass along to a SOCKS5 proxy that is greater than 255 bytes in
    length, it will switch to local name resolution in order to resolve the address before passing it on to
    the SOCKS5 proxy. However, due to a bug introduced in 2020, this local name resolution could fail due to a
    slow SOCKS5 handshake, causing curl to pass on the hostname greater than 255 bytes in length into the
    target buffer, leading to a heap overflow.  The advisory for CVE-2023-38545 gives an example exploitation
    scenario of a malicious HTTPS server redirecting to a specially crafted URL. While it might seem that an
    attacker would need to influence the slowness of the SOCKS5 handshake, the advisory states that server
    latency is likely slow enough to trigger this bug. (CVE-2023-38545)

  - close_altfile in filename.c in less before 606 omits shell_quote calls for LESSCLOSE. (CVE-2022-48624)

  - Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of
    Oracle Java SE (component: Hotspot). Supported versions that are affected are Oracle Java SE: 8u401,
    8u401-perf, 11.0.22, 17.0.10, 21.0.2, 22; Oracle GraalVM for JDK: 17.0.10, 21.0.2, 22; Oracle GraalVM

    with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle
    GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized ability to
    cause a partial denial of service (partial DOS) of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM
    Enterprise Edition. Note: This vulnerability can be exploited by using APIs in the specified Component,
    e.g., through a web service which supplies data to the APIs. This vulnerability also applies to Java
    deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets,
    that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox
    for security. (CVE-2024-21011)

  - Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of
    Oracle Java SE (component: Networking). Supported versions that are affected are Oracle Java SE: 11.0.22,
    17.0.10, 21.0.2, 22; Oracle GraalVM for JDK: 17.0.10, 21.0.2, 22; Oracle GraalVM Enterprise Edition:

    via multiple protocols to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise
    Edition. Successful attacks of this vulnerability can result in unauthorized update, insert or delete
    access to some of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition accessible
    data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java
    Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes
    from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java
    deployments, typically in servers, that load and run only trusted code (e.g., code installed by an
    administrator). (CVE-2024-21012)

  - Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of
    Oracle Java SE (component: Hotspot). Supported versions that are affected are Oracle Java SE: 8u401-perf,
    11.0.22, 17.0.10, 21.0.2, 22; Oracle GraalVM for JDK: 17.0.10, 21.0.2 and 22; Oracle GraalVM Enterprise
    Edition: 21.3.9. Difficult to exploit vulnerability allows unauthenticated attacker with network access

    (CVE-2024-21085)

  - Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of
    Oracle Java SE (component: Hotspot). Supported versions that are affected are Oracle Java SE: 8u401,
    8u401-perf, 11.0.22, 17.0.10, 21.0.2, 22; Oracle GraalVM for JDK: 17.0.10, 21.0.2, 22; Oracle GraalVM
    Enterprise Edition: 20.3.13 and 21.3.9. Difficult to exploit vulnerability allows unauthenticated attacker
    with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle

    Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java
    applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java
    sandbox for security. (CVE-2024-21094)

  - A flaw was found in Buildah (and subsequently Podman Build) which allows containers to mount arbitrary
    locations on the host filesystem into build containers. A malicious Containerfile can use a dummy image
    with a symbolic link to the root filesystem as a mount source and cause the mount operation to mount the
    host root filesystem inside the RUN step. The commands inside the RUN step will then have read-write
    access to the host filesystem, allowing for full container escape at build time. (CVE-2024-1753)

  - A flaw was found in GnuTLS. The Minerva attack is a cryptographic vulnerability that exploits
    deterministic behavior in systems like GnuTLS, leading to side-channel leaks. In specific scenarios, such
    as when using the GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE flag, it can result in a noticeable step in nonce size
    from 513 to 512 bits, exposing a potential timing side-channel. (CVE-2024-28834)

  - The DNS message parsing code in `named` includes a section whose computational complexity is overly high.
    It does not cause problems for typical DNS traffic, but crafted queries and responses may cause excessive
    CPU load on the affected `named` instance by exploiting this flaw. This issue affects both authoritative
    servers and recursive resolvers. This issue affects BIND 9 versions 9.0.0 through 9.16.45, 9.18.0 through
    9.18.21, 9.19.0 through 9.19.19, 9.9.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.45-S1, and 9.18.11-S1
    through 9.18.21-S1. (CVE-2023-4408)

  - Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote
    attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the
    KeyTrap issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the
    protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG
    records. (CVE-2023-50387)

  - The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276 guidance is skipped)
    allows remote attackers to cause a denial of service (CPU consumption for SHA-1 computations) via DNSSEC
    responses in a random subdomain attack, aka the NSEC3 issue. The RFC 5155 specification implies that an
    algorithm must perform thousands of iterations of a hash function in certain situations. (CVE-2023-50868)

  - The iconv() function in the GNU C Library versions 2.39 and older may overflow the output buffer passed to
    it by up to 4 bytes when converting strings to the ISO-2022-CN-EXT character set, which may be used to
    crash an application or overwrite a neighbouring variable. (CVE-2024-2961)

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