"The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has nss packages installed that are affected by
multiple vulnerabilities:

  - A flaw was found in the way NSS responded to an
    SSLv2-compatible ClientHello with a ServerHello that had
    an all-zero random. A man-in-the-middle attacker could
    use this flaw in a passive replay attack.
    (CVE-2018-12384)

  - The TLS implementation in Mozilla Network Security
    Services (NSS) does not properly consider timing side-
    channel attacks on a noncompliant MAC check operation
    during the processing of malformed CBC padding, which
    allows remote attackers to conduct distinguishing
    attacks and plaintext-recovery attacks via statistical
    analysis of timing data for crafted packets, a related
    issue to CVE-2013-0169. (CVE-2013-1620)

  - Mozilla Network Security Services (NSS) before 3.15.2
    does not ensure that data structures are initialized
    before read operations, which allows remote attackers to
    cause a denial of service or possibly have unspecified
    other impact via vectors that trigger a decryption
    failure. (CVE-2013-1739)

  - A flaw was found in the way TLS False Start was
    implemented in NSS. An attacker could use this flaw to
    potentially return unencrypted information from the
    server. (CVE-2013-1740)

  - Integer overflow in Mozilla Network Security Services
    (NSS) 3.15 before 3.15.3 allows remote attackers to
    cause a denial of service or possibly have unspecified
    other impact via a large size value. (CVE-2013-1741)

  - Mozilla Network Security Services (NSS) 3.14 before
    3.14.5 and 3.15 before 3.15.3 allows remote attackers to
    cause a denial of service or possibly have unspecified
    other impact via invalid handshake packets.
    (CVE-2013-5605)

  - The CERT_VerifyCert function in lib/certhigh/certvfy.c
    in Mozilla Network Security Services (NSS) 3.15 before
    3.15.3 provides an unexpected return value for an
    incompatible key-usage certificate when the
    CERTVerifyLog argument is valid, which might allow
    remote attackers to bypass intended access restrictions
    via a crafted certificate. (CVE-2013-5606)

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