The version of Juniper ScreenOS running on the remote host is 6.3.x prior to 6.3.0r22. It is, therefore, affected by multiple vulnerabilities in its bundled version of OpenSSL :

  - A denial of service vulnerability exists due to improper     validation of the content and length of the ASN1_TIME     string by the X509_cmp_time() function. A remote     attacker can exploit this, via a malformed certificate     and CRLs of various sizes, to cause a segmentation     fault, resulting in a denial of service condition. TLS     clients that verify CRLs are affected. TLS clients and     servers with client authentication enabled may be     affected if they use custom verification callbacks.
    (CVE-2015-1789)

  - A NULL pointer dereference flaw exists in the PKCS#7     parsing code due to incorrect handling of missing inner     'EncryptedContent'. This allows a remote attacker, via     specially crafted ASN.1-encoded PKCS#7 blobs with     missing content, to cause a denial of service condition     or other potential unspecified impacts. (CVE-2015-1790)

  - A double-free error exists due to a race condition that     occurs when a NewSessionTicket is received by a     multi-threaded client when attempting to reuse a     previous ticket. A remote attacker can exploit this to     cause a denial of service condition or other potential     unspecified impact. (CVE-2015-1791)

  - A flaw exists in the ASN1_TFLG_COMBINE implementation in     file tasn_dec.c related to handling malformed     X509_ATTRIBUTE structures. A remote attacker can exploit     this to cause a memory leak by triggering a decoding     failure in a PKCS#7 or CMS application, resulting in a     denial of service. (CVE-2015-3195)

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

This update for libopenssl0_9_8 fixes the following issues :

  - CVE-2016-0800 aka the 'DROWN' attack (bsc#968046):
    OpenSSL was vulnerable to a cross-protocol attack that     could lead to decryption of TLS sessions by using a     server supporting SSLv2 and EXPORT cipher suites as a     Bleichenbacher RSA padding oracle.

    This update changes the openssl library to :

  - Disable SSLv2 protocol support by default.

    This can be overridden by setting the environment     variable 'OPENSSL_ALLOW_SSL2' or by using     SSL_CTX_clear_options using the SSL_OP_NO_SSLv2 flag.

    Note that various services and clients had already     disabled SSL protocol 2 by default previously.

  - Disable all weak EXPORT ciphers by default. These can be     reenabled if required by old legacy software using the     environment variable 'OPENSSL_ALLOW_EXPORT'.

  - CVE-2016-0797 (bnc#968048): The BN_hex2bn() and     BN_dec2bn() functions had a bug that could result in an     attempt to de-reference a NULL pointer leading to     crashes. This could have security consequences if these     functions were ever called by user applications with     large untrusted hex/decimal data. Also, internal usage     of these functions in OpenSSL uses data from config     files or application command line arguments. If user     developed applications generated config file data based     on untrusted data, then this could have had security     consequences as well.

  - CVE-2016-0799 (bnc#968374) On many 64 bit systems, the     internal fmtstr() and doapr_outch() functions could     miscalculate the length of a string and attempt to     access out-of-bounds memory locations. These problems     could have enabled attacks where large amounts of     untrusted data is passed to the BIO_*printf functions.
    If applications use these functions in this way then     they could have been vulnerable. OpenSSL itself uses     these functions when printing out human-readable dumps     of ASN.1 data. Therefore applications that print this     data could have been vulnerable if the data is from     untrusted sources. OpenSSL command line applications     could also have been vulnerable when they print out     ASN.1 data, or if untrusted data is passed as command     line arguments. Libssl is not considered directly     vulnerable.

Versions of OpenSSL prior to 1.0.1n, or 1.0.2b are unpatched for the following vulnerabilities :

  - A man-in-the-middle vulnerability, known as Logjam, exists due to a flaw in the SSL/TLS protocol. A remote attacker can exploit this flaw to downgrade connections using ephemeral Diffie-Hellman key exchange to 512-bit export-grade cryptography. (CVE-2015-4000)

  - A denial of service vulnerability exists when processing an ECParameters structure due to an infinite loop that occurs when a specified curve is over a malformed binary polynomial field. A remote attacker can exploit this to perform a denial of service against any system that processes public keys, certificate requests, or certificates. This includes TLS clients and TLS servers with client authentication enabled. (CVE-2015-1788)

  - A denial of service vulnerability exists due to improper validation of the content and length of the ASN1_TIME string by the X509_cmp_time() function. A remote attacker can exploit this, via a malformed certificate and CRLs of various sizes, to cause a segmentation fault, resulting in a denial of service condition.

  - A denial of service vulnerability exists in the CMS code due to an infinite loop that occurs when verifying a signedData message. A remote attacker can exploit this to cause a denial of service condition. (CVE-2015-1792)

  - An off-by-one overflow condition affects the BN_rand() function in 'crypto/bn/random.c'. The issue is triggered as user-supplied input is not properly validated. This may allow an attacker to cause a buffer overflow, resulting in a denial of service.

  - An off-by-one overflow condition affects the BN_bn2hex() function in 'crypto/bn/bn_print.c'. The issue is triggered as user-supplied input is not properly validated. This may allow an attacker to cause a buffer overflow, potentially resulting in a denial of service or another, more severe impact.
