"The version of AOS installed on the remote host is prior to 6.7.1. It is, therefore, affected by multiple
vulnerabilities as referenced in the NXSA-AOS-6.7.1 advisory.

  - The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path,
    leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in
    /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an
    incomplete fix for CVE-2016-10009. (CVE-2023-38408)

  - An issue in the urllib.parse component of Python before 3.11.4 allows attackers to bypass blocklisting
    methods by supplying a URL that starts with blank characters. (CVE-2023-24329)

  - Integer Overflow or Wraparound vulnerability in apr_base64 functions of Apache Portable Runtime Utility
    (APR-util) allows an attacker to write beyond bounds of a buffer. This issue affects Apache Portable
    Runtime Utility (APR-util) 1.6.1 and prior versions. (CVE-2022-25147)

  - Every `named` instance configured to run as a recursive resolver maintains a cache database holding the
    responses to the queries it has recently sent to authoritative servers. The size limit for that cache
    database can be configured using the `max-cache-size` statement in the configuration file; it defaults to
    90% of the total amount of memory available on the host. When the size of the cache reaches 7/8 of the
    configured limit, a cache-cleaning algorithm starts to remove expired and/or least-recently used RRsets
    from the cache, to keep memory use below the configured limit. It has been discovered that the
    effectiveness of the cache-cleaning algorithm used in `named` can be severely diminished by querying the
    resolver for specific RRsets in a certain order, effectively allowing the configured `max-cache-size`
    limit to be significantly exceeded. This issue affects BIND 9 versions 9.11.0 through 9.16.41, 9.18.0
    through 9.18.15, 9.19.0 through 9.19.13, 9.11.3-S1 through 9.16.41-S1, and 9.18.11-S1 through 9.18.15-S1.
    (CVE-2023-2828)

  - An issue was discovered in GNU Emacs through 28.2. htmlfontify.el has a command injection vulnerability.
    In the hfy-istext-command function, the parameter file and parameter srcdir come from external input, and
    parameters are not escaped. If a file name or directory name contains shell metacharacters, code may be
    executed. (CVE-2022-48339)

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