"The version of AOS installed on the remote host is prior to 6.6.2.5. It is, therefore, affected by multiple
vulnerabilities as referenced in the NXSA-AOS-6.6.2.5 advisory.

  - An attacker could construct a PKCS 12 cert bundle in such a way that could allow for arbitrary memory
    writes via PKCS 12 Safe Bag attributes being mishandled. This vulnerability affects Firefox < 110,
    Thunderbird < 102.8, and Firefox ESR < 102.8. (CVE-2023-0767)

  - There is a type confusion vulnerability relating to X.400 address processing inside an X.509 GeneralName.
    X.400 addresses were parsed as an ASN1_STRING but the public structure definition for GENERAL_NAME
    incorrectly specified the type of the x400Address field as ASN1_TYPE. This field is subsequently
    interpreted by the OpenSSL function GENERAL_NAME_cmp as an ASN1_TYPE rather than an ASN1_STRING. When CRL
    checking is enabled (i.e. the application sets the X509_V_FLAG_CRL_CHECK flag), this vulnerability may
    allow an attacker to pass arbitrary pointers to a memcmp call, enabling them to read memory contents or
    enact a denial of service. In most cases, the attack requires the attacker to provide both the certificate
    chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these
    inputs, the other input must already contain an X.400 address as a CRL distribution point, which is
    uncommon. As such, this vulnerability is most likely to only affect applications which have implemented
    their own functionality for retrieving CRLs over a network. (CVE-2023-0286)

  - zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow in inflate in inflate.c via a
    large gzip header extra field. NOTE: only applications that call inflateGetHeader are affected. Some
    common applications bundle the affected zlib source code but may be unable to call inflateGetHeader (e.g.,
    see the nodejs/node reference). (CVE-2022-37434)

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