"The version of AOS installed on the remote host is prior to 6.5.2. It is, therefore, affected by multiple
vulnerabilities as referenced in the NXSA-AOS-6.5.2 advisory.

  - http.client in Python 3.x before 3.5.10, 3.6.x before 3.6.12, 3.7.x before 3.7.9, and 3.8.x before 3.8.5
    allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR
    and LF control characters in the first argument of HTTPConnection.request. (CVE-2020-26116)

  - urllib3 before 1.25.9 allows CRLF injection if the attacker controls the HTTP request method, as
    demonstrated by inserting CR and LF control characters in the first argument of putrequest(). NOTE: this
    is similar to CVE-2020-26116. (CVE-2020-26137)

  - Python 3.x through 3.9.1 has a buffer overflow in PyCArg_repr in _ctypes/callproc.c, which may lead to
    remote code execution in certain Python applications that accept floating-point numbers as untrusted
    input, as demonstrated by a 1e300 argument to c_double.from_param. This occurs because sprintf is used
    unsafely. (CVE-2021-3177)

  - An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the
    attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content
    to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing
    filenames with two or more newlines where selected content and the target file names are embedded in
    crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write
    arbitrary files on the system. (CVE-2022-1271)

  - A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged
    user to gain root privileges. The bug allows to build several exploit primitives such as kernel address
    information leak, arbitrary execution, etc. (CVE-2022-1729)

  - Incomplete cleanup of multi-core shared buffers for some Intel(R) Processors may allow an authenticated
    user to potentially enable information disclosure via local access. (CVE-2022-21123)

  - Incomplete cleanup of microarchitectural fill buffers on some Intel(R) Processors may allow an
    authenticated user to potentially enable information disclosure via local access. (CVE-2022-21125)

  - Incomplete cleanup in specific special register write operations for some Intel(R) Processors may allow an
    authenticated user to potentially enable information disclosure via local access. (CVE-2022-21166)

  - Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE
    (component: Hotspot). Supported versions that are affected are Oracle Java SE: 7u343, 8u333, 11.0.15.1,
    17.0.3.1, 18.0.1.1; Oracle GraalVM Enterprise Edition: 20.3.6, 21.3.2 and 22.1.0. Easily exploitable
    vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise

    APIs in the specified Component, e.g., through a web service which supplies data to the APIs.
    (CVE-2022-21626)

  - Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE
    (component: Lightweight HTTP Server). Supported versions that are affected are Oracle Java SE: 8u341,
    8u345-perf, 11.0.16.1, 17.0.4.1, 19; Oracle GraalVM Enterprise Edition: 20.3.7, 21.3.3 and 22.2.0. Easily
    exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise
    Oracle Java SE, 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
    Enterprise Edition. 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-2022-21628)

  - A use-after-free vulnerability was found in systemd. This issue occurs due to the on_stream_io() function
    and dns_stream_complete() function in 'resolved-dns-stream.c' not incrementing the reference counting for
    the DnsStream object. Therefore, other functions and callbacks called can dereference the DNSStream
    object, causing the use-after-free when the reference is still used later. (CVE-2022-2526)

  - An issue was discovered in rsync before 3.2.5 that allows malicious remote servers to write arbitrary
    files inside the directories of connecting peers. The server chooses which files/directories are sent to
    the client. However, the rsync client performs insufficient validation of file names. A malicious rsync
    server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the rsync client target directory
    and subdirectories (for example, overwrite the .ssh/authorized_keys file). (CVE-2022-29154)

  - VMware Tools (12.0.0, 11.x.y and 10.x.y) contains a local privilege escalation vulnerability. A malicious
    actor with local non-administrative access to the Guest OS can escalate privileges as a root user in the
    virtual machine. (CVE-2022-31676)

  - The Apache Xalan Java XSLT library is vulnerable to an integer truncation issue when processing malicious
    XSLT stylesheets. This can be used to corrupt Java class files generated by the internal XSLTC compiler
    and execute arbitrary Java bytecode. The Apache Xalan Java project is dormant and in the process of being
    retired. No future releases of Apache Xalan Java to address this issue are expected. Note: Java runtimes
    (such as OpenJDK) include repackaged copies of Xalan. (CVE-2022-34169)

  - In Apache Tomcat 10.1.0-M1 to 10.1.0-M16, 10.0.0-M1 to 10.0.22, 9.0.30 to 9.0.64 and 8.5.50 to 8.5.81 the
    Form authentication example in the examples web application displayed user provided data without
    filtering, exposing a XSS vulnerability. (CVE-2022-34305)

  - By spoofing the target resolver with responses that have a malformed ECDSA signature, an attacker can
    trigger a small memory leak. It is possible to gradually erode available memory to the point where named
    crashes for lack of resources. (CVE-2022-38177)

  - By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can
    trigger a small memory leak. It is possible to gradually erode available memory to the point where named
    crashes for lack of resources. (CVE-2022-38178)

  - libexpat before 2.4.9 has a use-after-free in the doContent function in xmlparse.c. (CVE-2022-40674)

  - multipath-tools 0.7.0 through 0.9.x before 0.9.2 allows local users to obtain root access, as exploited
    alone or in conjunction with CVE-2022-41973. Local users able to write to UNIX domain sockets can bypass
    access controls and manipulate the multipath setup. This can lead to local privilege escalation to root.
    This occurs because an attacker can repeat a keyword, which is mishandled because arithmetic ADD is used
    instead of bitwise OR. (CVE-2022-41974)

  - If Apache Tomcat 8.5.0 to 8.5.82, 9.0.0-M1 to 9.0.67, 10.0.0-M1 to 10.0.26 or 10.1.0-M1 to 10.1.0 was
    configured to ignore invalid HTTP headers via setting rejectIllegalHeader to false (the default for 8.5.x
    only), Tomcat did not reject a request containing an invalid Content-Length header making a request
    smuggling attack possible if Tomcat was located behind a reverse proxy that also failed to reject the
    request with the invalid header. (CVE-2022-42252)

  - PAC parsing in MIT Kerberos 5 (aka krb5) before 1.19.4 and 1.20.x before 1.20.1 has integer overflows that
    may lead to remote code execution (in KDC, kadmind, or a GSS or Kerberos application server) on 32-bit
    platforms (which have a resultant heap-based buffer overflow), and cause a denial of service on other
    platforms. This occurs in krb5_pac_parse in lib/krb5/krb/pac.c. Heimdal before 7.7.1 has a similar bug.
    (CVE-2022-42898)
