openssl was updated to fix six security issues.

The following vulnerabilities were fixed :

  - CVE-2015-4000: The Logjam Attack / weakdh.org. Rject     connections with DH parameters shorter than 768 bits,     generates 2048-bit DH parameters by default.
    (boo#931698)

  - CVE-2015-1788: Malformed ECParameters causes infinite     loop (boo#934487)

  - CVE-2015-1789: Exploitable out-of-bounds read in     X509_cmp_time (boo#934489)

  - CVE-2015-1790: PKCS7 crash with missing EnvelopedContent     (boo#934491)

  - CVE-2015-1792: CMS verify infinite loop with unknown     hash function (boo#934493)

  - CVE-2015-1791: race condition in NewSessionTicket     (boo#933911)

  - CVE-2015-3216: Crash in ssleay_rand_bytes due to locking     regression (boo#933898)

OpenSSL 0.9.8j was updated to fix several security issues.

CVE-2015-4000: The Logjam Attack ( weakdh.org ) has been addressed by rejecting connections with DH parameters shorter than 1024 bits. We now also generate 2048-bit DH parameters by default.

CVE-2015-1788: Malformed ECParameters could cause an infinite loop.

CVE-2015-1789: An out-of-bounds read in X509_cmp_time was fixed.

CVE-2015-1790: A PKCS7 decoder crash with missing EnvelopedContent was fixed.

CVE-2015-1792: A CMS verification infinite loop when using an unknown hash function was fixed.

CVE-2015-1791: Fixed a race condition in NewSessionTicket creation.

CVE-2015-3216: Fixed a potential crash in ssleay_rand_bytes due to locking regression.

fixed a timing side channel in RSA decryption (bnc#929678)

Additional changes :

In the default SSL cipher string EXPORT ciphers are now disabled. This will only get active if applications get rebuilt and actually use this string. (bnc#931698)

Added the ECC ciphersuites to the DEFAULT cipher class (bnc#879179)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

libressl was updated to version 2.2.1 to fix 16 security issues.

LibreSSL is a fork of OpenSSL. Because of that CVEs affecting OpenSSL often also affect LibreSSL.

These security issues were fixed :

  - CVE-2014-3570: The BN_sqr implementation in OpenSSL     before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before     1.0.1k did not properly calculate the square of a BIGNUM     value, which might make it easier for remote attackers     to defeat cryptographic protection mechanisms via     unspecified vectors, related to crypto/bn/asm/mips.pl,     crypto/bn/asm/x86_64-gcc.c, and crypto/bn/bn_asm.c     (bsc#912296).

  - CVE-2014-3572: The ssl3_get_key_exchange function in     s3_clnt.c in OpenSSL before 0.9.8zd, 1.0.0 before     1.0.0p, and 1.0.1 before 1.0.1k allowed remote SSL     servers to conduct ECDHE-to-ECDH downgrade attacks and     trigger a loss of forward secrecy by omitting the     ServerKeyExchange message (bsc#912015).

  - CVE-2015-1792: The do_free_upto function in     crypto/cms/cms_smime.c in OpenSSL before 0.9.8zg, 1.0.0     before 1.0.0s, 1.0.1 before 1.0.1n, and 1.0.2 before     1.0.2b allowed remote attackers to cause a denial of     service (infinite loop) via vectors that trigger a NULL     value of a BIO data structure, as demonstrated by an     unrecognized X.660 OID for a hash function (bsc#934493).

  - CVE-2014-8275: OpenSSL before 0.9.8zd, 1.0.0 before     1.0.0p, and 1.0.1 before 1.0.1k did not enforce certain     constraints on certificate data, which allowed remote     attackers to defeat a fingerprint-based     certificate-blacklist protection mechanism by including     crafted data within a certificate's unsigned portion,     related to crypto/asn1/a_verify.c,     crypto/dsa/dsa_asn1.c, crypto/ecdsa/ecs_vrf.c, and     crypto/x509/x_all.c (bsc#912018).

  - CVE-2015-0209: Use-after-free vulnerability in the     d2i_ECPrivateKey function in crypto/ec/ec_asn1.c in     OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1     before 1.0.1m, and 1.0.2 before 1.0.2a might allowed     remote attackers to cause a denial of service (memory     corruption and application crash) or possibly have     unspecified other impact via a malformed Elliptic Curve     (EC) private-key file that is improperly handled during     import (bsc#919648).

  - CVE-2015-1789: The X509_cmp_time function in     crypto/x509/x509_vfy.c in OpenSSL before 0.9.8zg, 1.0.0     before 1.0.0s, 1.0.1 before 1.0.1n, and 1.0.2 before     1.0.2b allowed remote attackers to cause a denial of     service (out-of-bounds read and application crash) via a     crafted length field in ASN1_TIME data, as demonstrated     by an attack against a server that supports client     authentication with a custom verification callback     (bsc#934489).

  - CVE-2015-1788: The BN_GF2m_mod_inv function in     crypto/bn/bn_gf2m.c in OpenSSL before 0.9.8s, 1.0.0     before 1.0.0e, 1.0.1 before 1.0.1n, and 1.0.2 before     1.0.2b did not properly handle ECParameters structures     in which the curve is over a malformed binary polynomial     field, which allowed remote attackers to cause a denial     of service (infinite loop) via a session that used an     Elliptic Curve algorithm, as demonstrated by an attack     against a server that supports client authentication     (bsc#934487).

  - CVE-2015-1790: The PKCS7_dataDecodefunction in     crypto/pkcs7/pk7_doit.c in OpenSSL before 0.9.8zg, 1.0.0     before 1.0.0s, 1.0.1 before 1.0.1n, and 1.0.2 before     1.0.2b allowed remote attackers to cause a denial of     service (NULL pointer dereference and application crash)     via a PKCS#7 blob that used ASN.1 encoding and lacks     inner EncryptedContent data (bsc#934491).

  - CVE-2015-0287: The ASN1_item_ex_d2i function in     crypto/asn1/tasn_dec.c in OpenSSL before 0.9.8zf, 1.0.0     before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before     1.0.2a did not reinitialize CHOICE and ADB data     structures, which might allowed attackers to cause a     denial of service (invalid write operation and memory     corruption) by leveraging an application that relies on     ASN.1 structure reuse (bsc#922499).

  - CVE-2015-0286: The ASN1_TYPE_cmp function in     crypto/asn1/a_type.c in OpenSSL before 0.9.8zf, 1.0.0     before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before     1.0.2a did not properly perform boolean-type     comparisons, which allowed remote attackers to cause a     denial of service (invalid read operation and     application crash) via a crafted X.509 certificate to an     endpoint that used the certificate-verification feature     (bsc#922496).

  - CVE-2015-0289: The PKCS#7 implementation in OpenSSL     before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before     1.0.1m, and 1.0.2 before 1.0.2a did not properly handle     a lack of outer ContentInfo, which allowed attackers to     cause a denial of service (NULL pointer dereference and     application crash) by leveraging an application that     processes arbitrary PKCS#7 data and providing malformed     data with ASN.1 encoding, related to     crypto/pkcs7/pk7_doit.c and crypto/pkcs7/pk7_lib.c     (bsc#922500).

  - CVE-2015-0288: The X509_to_X509_REQ function in     crypto/x509/x509_req.c in OpenSSL before 0.9.8zf, 1.0.0     before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before     1.0.2a might allowed attackers to cause a denial of     service (NULL pointer dereference and application crash)     via an invalid certificate key (bsc#920236).

  - CVE-2014-8176: The dtls1_clear_queues function in     ssl/d1_lib.c in OpenSSL before 0.9.8za, 1.0.0 before     1.0.0m, and 1.0.1 before 1.0.1h frees data structures     without considering that application data can arrive     between a ChangeCipherSpec message and a Finished     message, which allowed remote DTLS peers to cause a     denial of service (memory corruption and application     crash) or possibly have unspecified other impact via     unexpected application data (bsc#934494).

  - CVE-2015-4000: The TLS protocol 1.2 and earlier, when a     DHE_EXPORT ciphersuite is enabled on a server but not on     a client, did not properly convey a DHE_EXPORT choice,     which allowed man-in-the-middle attackers to conduct     cipher-downgrade attacks by rewriting a ClientHello with     DHE replaced by DHE_EXPORT and then rewriting a     ServerHello with DHE_EXPORT replaced by DHE, aka the     'Logjam' issue (bsc#931600).

  - CVE-2015-0205: The ssl3_get_cert_verify function in     s3_srvr.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1     before 1.0.1k accepts client authentication with a     Diffie-Hellman (DH) certificate without requiring a     CertificateVerify message, which allowed remote     attackers to obtain access without knowledge of a     private key via crafted TLS Handshake Protocol traffic     to a server that recognizes a Certification Authority     with DH support (bsc#912293).

  - CVE-2015-0206: Memory leak in the dtls1_buffer_record     function in d1_pkt.c in OpenSSL 1.0.0 before 1.0.0p and     1.0.1 before 1.0.1k allowed remote attackers to cause a     denial of service (memory consumption) by sending many     duplicate records for the next epoch, leading to failure     of replay detection (bsc#912292).

The X509_cmp_time function in crypto/x509/x509_vfy.c in OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted length field in ASN1_TIME data, as demonstrated by an attack against a server that supports client authentication with a custom verification callback.
(CVE-2015-1789)

The Cisco Application Control Engine (ACE) software installed on the remote Cisco ACE 4710 device or ACE30 module is version A5 prior to A5(3.3). It is, therefore, affected by multiple vulnerabilities :

  - An invalid free memory error exists due to improper     validation of user-supplied input when a DTLS peer     receives application data between ChangeCipherSpec and     Finished messages. A remote attacker can exploit this to     corrupt memory, resulting in a denial of service or     the execution of arbitrary code. (CVE-2014-8176)

  - 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. 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 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)

  - The symmetric-key feature in the receive function     requires a correct message authentication code (MAC)     only if the MAC field has a nonzero length. This makes     it easier for a man-in-the-middle attacker to spoof     packets by omitting the MAC. (CVE-2015-1798)

  - A flaw exists in the symmetric-key feature in the     receive function when handling a specially crafted     packet sent to one of two hosts that are peering with     each other. This allows an attacker to cause the next     attempt by the servers to synchronize to fail.
    (CVE-2015-1799)

  - 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 flaw exists in the TLS 1.x implementation in the     Cavium SDK due to a failure to check the first byte of     the padding bytes. A man-in-the-middle attacker can     exploit this, by sending specially crafted requests to     the server, to induce requests that allow determining     the plaintext chunks of data. This vulnerability is a     variant of the POODLE attack. (CVE-2015-4595)

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.

  - The package was updated to 0.9.8zh :

  - fixes many security vulnerabilities (not separately     listed): CVE-2015-3195, CVE-2015-1788, CVE-2015-1789,     CVE-2015-1790, CVE-2015-1792, CVE-2015-1791,     CVE-2015-0286, CVE-2015-0287, CVE-2015-0289,     CVE-2015-0293, CVE-2015-0209, CVE-2015-0288,     CVE-2014-3571, CVE-2014-3569, CVE-2014-3572,     CVE-2015-0204, CVE-2014-8275, CVE-2014-3570,     CVE-2014-3567, CVE-2014-3568, CVE-2014-3566,     CVE-2014-3510, CVE-2014-3507, CVE-2014-3506,     CVE-2014-3505, CVE-2014-3508, CVE-2014-0224,     CVE-2014-0221, CVE-2014-0195, CVE-2014-3470,     CVE-2014-0076, CVE-2013-0169, CVE-2013-0166

  - avoid running OPENSSL_config twice. This avoids breaking     engine loading. (boo#952871, boo#967787)

  - fix CVE-2015-3197 (boo#963415)

  - SSLv2 doesn't block disabled ciphers

  - FontParser
  - Libinfo
  - libxml2
  - OpenSSL
  - perl
  - PostgreSQL
  - QL Office
  - Quartz Composer Framework
  - QuickTime 7
  - SceneKit

Note that successful exploitation of the most serious issues can result in arbitrary code execution.
