  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. Incorrectly using of pointer arithmetic for heap-buffer boundary checks which might allow remote attackers to cause a denial of service or possibly
  have unspecified other impact by leveraging unexpected malloc behavior, related to s3_srvr.c, ssl_sess.c, and t1_lib.c.

  2. Improperly use of constant-time operations in crypto/dsa/dsa_oss.c which allow local users to breach the DSA private key.");

  script_tag(name:"impact", value:"Successful exploitation will allow remote attackers to cause a denial of service and will allow local users to discover a DSA private key
  via a timing side-channel attack");

  script_tag(name:"affected", value:"OpenSSL 1.0.2h and previous versions.");

  script_tag(name:"solution", value:"For undefined pointer arithmetic vulnerability,
  there is a fix available for OpenSSL 1.0.2 and OpenSSL 1.0.1. To prevent DSA private key breach, a fix is available, too.");
