  script_tag(name:"vuldetect", value:"Checks if a vulnerable version is present on the target host.");

  script_tag(name:"insight", value:"Multiple flaws are due to:

  1. TLS connections using *-CHACHA20-POLY1305 ciphersuites are susceptible to a DoS attack by corrupting larger payloads. This can result in an OpenSSL crash.

  2. Applications parsing invalid CMS structures can crash with a NULL pointer dereference.
  This is caused  by a bug in the handling of the ASN.1 CHOICE type in OpenSSL 1.1.0 which can result in a NULL value being
  passed to the structure callback if an attempt is made to free certain invalid encodings. Only CHOICE structures
  using a callback which do not handle NULL value are affected.");

  script_tag(name:"impact", value:"Successful exploitation will allow remote attackers to cause a denial of service.");

  script_tag(name:"affected", value:"OpenSSL 1.1.0 versions prior to 1.1.0c");
