Refer to the Release Notes for information on the most significant bug fixes and enhancements included in this release.

Security Fix(es) :

* A flaw was found in the way OpenSSL encoded certain ASN.1 data structures. An attacker could use this flaw to create a specially crafted certificate which, when verified or re-encoded by OpenSSL, could cause it to crash, or execute arbitrary code using the permissions of the user running an application compiled against the OpenSSL library. (CVE-2016-2108)

* It was found that the length checks prior to writing to the target buffer for creating a virtual host mapping rule did not take account of the length of the virtual host name, creating the potential for a buffer overflow. (CVE-2016-6808)

* It was discovered that OpenSSL did not always use constant time operations when computing Digital Signature Algorithm (DSA) signatures. A local attacker could possibly use this flaw to obtain a private DSA key belonging to another user or service running on the same system. (CVE-2016-2178)

* Multiple integer overflow flaws were found in the way OpenSSL performed pointer arithmetic. A remote attacker could possibly use these flaws to cause a TLS/SSL server or client using OpenSSL to crash. (CVE-2016-2177)

* It was discovered that specifying configuration with a JVMRoute path longer than 80 characters will cause segmentation fault leading to a server crash. (CVE-2016-4459)

* An error was found in protocol parsing logic of mod_cluster load balancer Apache HTTP Server modules. An attacker could use this flaw to cause a Segmentation Fault in the serving httpd process.

The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2016-686:04 advisory.

    The OpenSSL toolkit provides support for secure communications between     machines. OpenSSL includes a certificate management tool and shared     libraries which provide various cryptographic algorithms and     protocols.
    Security issues fixed with this release:
    CVE-2016-2177     OpenSSL through 1.0.2h incorrectly uses pointer arithmetic for     heap-buffer boundary checks, which might allow remote attackers to     cause a denial of service (integer overflow and application crash) or     possibly have unspecified other impact by leveraging unexpected malloc     behavior, related to s3_srvr.c, ssl_sess.c, and t1_lib.c.
    CVE-2016-2178     The dsa_sign_setup function in crypto/dsa/dsa_ossl.c in OpenSSL     through 1.0.2h does not properly ensure the use of constant-time     operations, which makes it easier for local users to discover a DSA     private key via a timing side-channel attack.
    CVE-2016-2179     The DTLS implementation in OpenSSL before 1.1.0 does not properly     restrict the lifetime of queue entries associated with unused     out-of-order messages, which allows remote attackers to cause a denial     of service (memory consumption) by maintaining many crafted DTLS     sessions simultaneously, related to d1_lib.c, statem_dtls.c,     statem_lib.c, and statem_srvr.c.
    CVE-2016-2180     The TS_OBJ_print_bio function in crypto/ts/ts_lib.c in the X.509     Public Key Infrastructure Time-Stamp Protocol (TSP) implementation in     OpenSSL through 1.0.2h allows remote attackers to cause a denial of     service (out-of-bounds read and application crash) via a crafted     time-stamp file that is mishandled by the openssl ts command.
    CVE-2016-2181     The Anti-Replay feature in the DTLS implementation in OpenSSL before     1.1.0 mishandles early use of a new epoch number in conjunction with a     large sequence number, which allows remote attackers to cause a denial     of service (false-positive packet drops) via spoofed DTLS records,     related to rec_layer_d1.c and ssl3_record.c.
    CVE-2016-2182     The BN_bn2dec function in crypto/bn/bn_print.c in OpenSSL before 1.1.0     does not properly validate division results, which allows remote     attackers to cause a denial of service (out-of-bounds write and     application crash) or possibly have unspecified other impact via     unknown vectors.
    CVE-2016-6302     The tls_decrypt_ticket function in ssl/t1_lib.c in OpenSSL before     1.1.0 does not consider the HMAC size during validation of the ticket     length, which allows remote attackers to cause a denial of service via     a ticket that is too short.
    CVE-2016-6304     Multiple memory leaks in t1_lib.c in OpenSSL before 1.0.1u, 1.0.2     before 1.0.2i, and 1.1.0 before 1.1.0a allow remote attackers to cause     a denial of service (memory consumption) via large OCSP Status Request     extensions.
    CVE-2016-6306     The certificate parser in OpenSSL before 1.0.1u and 1.0.2 before     1.0.2i might allow remote attackers to cause a denial of service     (out-of-bounds read) via crafted certificate operations, related to     s3_clnt.c and s3_srvr.c.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

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

Mitre reports :

OpenSSL through 1.0.2h incorrectly uses pointer arithmetic for heap-buffer boundary checks, which might allow remote attackers to cause a denial of service (integer overflow and application crash) or possibly have unspecified other impact by leveraging unexpected malloc behavior, related to s3_srvr.c, ssl_sess.c, and t1_lib.c.

According to the versions of the openssl098e package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - An integer underflow flaw, leading to a buffer     overflow, was found in the way OpenSSL decoded     malformed Base64-encoded inputs. An attacker able to     make an application using OpenSSL decode a specially     crafted Base64-encoded input (such as a PEM file) could     use this flaw to cause the application to crash. Note:
    this flaw is not exploitable via the TLS/SSL protocol     because the data being transferred is not     Base64-encoded.(CVE-2015-0292)

  - An out-of-bounds read flaw was found in the     X509_cmp_time() function of OpenSSL, which is used to     test the expiry dates of SSL/TLS certificates. An     attacker could possibly use a specially crafted SSL/TLS     certificate or CRL (Certificate Revocation List), which     when parsed by an application would cause that     application to crash.(CVE-2015-1789)

  - A memory leak vulnerability was found in the way     OpenSSL parsed PKCS#7 and CMS data. A remote attacker     could use this flaw to cause an application that parses     PKCS#7 or CMS data from untrusted sources to use an     excessive amount of memory and possibly     crash.(CVE-2015-3195)

  - OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1     before 1.0.1k allows remote attackers to cause a denial     of service (NULL pointer dereference and application     crash) via a crafted DTLS message that is processed     with a different read operation for the handshake     header than for the handshake body, related to the     dtls1_get_record function in d1_pkt.c and the     ssl3_read_n function in s3_pkt.c.(CVE-2014-3571)

  - OpenSSL through 1.0.2h incorrectly uses pointer     arithmetic for heap-buffer boundary checks, which might     allow remote attackers to cause a denial of service     (integer overflow and application crash) or possibly     have unspecified other impact by leveraging unexpected     malloc behavior, related to s3_srvr.c, ssl_sess.c, and     t1_lib.c.(CVE-2016-2177)

  - An integer overflow flaw, leading to a buffer overflow,     was found in the way the EVP_EncodeUpdate() function of     OpenSSL parsed very large amounts of input data. A     remote attacker could use this flaw to crash an     application using OpenSSL or, possibly, execute     arbitrary code with the permissions of the user running     that application.(CVE-2016-2105)

  - An integer overflow flaw, leading to a buffer overflow,     was found in the way the EVP_EncryptUpdate() function     of OpenSSL parsed very large amounts of input data. A     remote attacker could use this flaw to crash an     application using OpenSSL or, possibly, execute     arbitrary code with the permissions of the user running     that application.(CVE-2016-2106)

  - A flaw was found in the way OpenSSL encoded certain     ASN.1 data structures. An attacker could use this flaw     to create a specially crafted certificate which, when     verified or re-encoded by OpenSSL, could cause it to     crash, or execute arbitrary code using the permissions     of the user running an application compiled against the     OpenSSL library.(CVE-2016-2108)

  - A denial of service flaw was found in the way OpenSSL     parsed certain ASN.1-encoded data from BIO (OpenSSL's     I/O abstraction) inputs. An application using OpenSSL     that accepts untrusted ASN.1 BIO input could be forced     to allocate an excessive amount of data.(CVE-2016-2109)

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

An update for openssl is now available for Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library.

Security Fix(es) :

* A memory leak flaw was found in the way OpenSSL handled TLS status request extension data during session renegotiation. A remote attacker could cause a TLS server using OpenSSL to consume an excessive amount of memory and, possibly, exit unexpectedly after exhausting all available memory, if it enabled OCSP stapling support. (CVE-2016-6304)

* It was discovered that OpenSSL did not always use constant time operations when computing Digital Signature Algorithm (DSA) signatures. A local attacker could possibly use this flaw to obtain a private DSA key belonging to another user or service running on the same system. (CVE-2016-2178)

* It was discovered that the Datagram TLS (DTLS) implementation could fail to release memory in certain cases. A malicious DTLS client could cause a DTLS server using OpenSSL to consume an excessive amount of memory and, possibly, exit unexpectedly after exhausting all available memory. (CVE-2016-2179)

* A flaw was found in the Datagram TLS (DTLS) replay protection implementation in OpenSSL. A remote attacker could possibly use this flaw to make a DTLS server using OpenSSL to reject further packets sent from a DTLS client over an established DTLS connection.
(CVE-2016-2181)

* An out of bounds write flaw was discovered in the OpenSSL BN_bn2dec() function. An attacker able to make an application using OpenSSL to process a large BIGNUM could cause the application to crash or, possibly, execute arbitrary code. (CVE-2016-2182)

* A flaw was found in the DES/3DES cipher was used as part of the TLS/SSL protocol. A man-in-the-middle attacker could use this flaw to recover some plaintext data by capturing large amounts of encrypted traffic between TLS/ SSL server and client if the communication used a DES/3DES based ciphersuite. (CVE-2016-2183)

This update mitigates the CVE-2016-2183 issue by lowering priority of DES cipher suites so they are not preferred over cipher suites using AES. For compatibility reasons, DES cipher suites remain enabled by default and included in the set of cipher suites identified by the HIGH cipher string. Future updates may move them to MEDIUM or not enable them by default.

* An integer underflow flaw leading to a buffer over-read was found in the way OpenSSL parsed TLS session tickets. A remote attacker could use this flaw to crash a TLS server using OpenSSL if it used SHA-512 as HMAC for session tickets. (CVE-2016-6302)

* Multiple integer overflow flaws were found in the way OpenSSL performed pointer arithmetic. A remote attacker could possibly use these flaws to cause a TLS/SSL server or client using OpenSSL to crash. (CVE-2016-2177)

* An out of bounds read flaw was found in the way OpenSSL formatted Public Key Infrastructure Time-Stamp Protocol data for printing. An attacker could possibly cause an application using OpenSSL to crash if it printed time stamp data from the attacker. (CVE-2016-2180)

* Multiple out of bounds read flaws were found in the way OpenSSL handled certain TLS/SSL protocol handshake messages. A remote attacker could possibly use these flaws to crash a TLS/SSL server or client using OpenSSL. (CVE-2016-6306)

The version of MySQL running on the remote host is 5.7.x prior to 5.7.16. It is, therefore, affected by multiple vulnerabilities :

  - Multiple integer overflow conditions exist in s3_srvr.c,     ssl_sess.c, and t1_lib.c due to improper use of pointer     arithmetic for heap-buffer boundary checks. An     unauthenticated, remote attacker can exploit this to     cause a denial of service. (CVE-2016-2177)

  - An information disclosure vulnerability exists in the     dsa_sign_setup() function in dsa_ossl.c due to a failure     to properly ensure the use of constant-time operations.
    An unauthenticated, remote attacker can exploit this,     via a timing side-channel attack, to disclose DSA key     information. (CVE-2016-2178)

  - A denial of service vulnerability exists in the DTLS     implementation due to a failure to properly restrict the     lifetime of queue entries associated with unused     out-of-order messages. An unauthenticated, remote     attacker can exploit this, by maintaining multiple     crafted DTLS sessions simultaneously, to exhaust memory.
    (CVE-2016-2179)

  - An out-of-bounds read error exists in the X.509 Public     Key Infrastructure Time-Stamp Protocol (TSP)     implementation. An unauthenticated, remote attacker can     exploit this, via a crafted time-stamp file that is     mishandled by the 'openssl ts' command, to cause     denial of service or to disclose sensitive information.
    (CVE-2016-2180)

  - A denial of service vulnerability exists in the     Anti-Replay feature in the DTLS implementation due to     improper handling of epoch sequence numbers in records.
    An unauthenticated, remote attacker can exploit this,     via spoofed DTLS records, to cause legitimate packets to     be dropped. (CVE-2016-2181)

  - An overflow condition exists in the BN_bn2dec() function     in bn_print.c due to improper validation of     user-supplied input when handling BIGNUM values. An     unauthenticated, remote attacker can exploit this to     crash the process. (CVE-2016-2182)

  - A vulnerability exists, known as SWEET32, in the 3DES     and Blowfish algorithms due to the use of weak 64-bit     block ciphers by default. A man-in-the-middle attacker     who has sufficient resources can exploit this     vulnerability, via a 'birthday' attack, to detect a     collision that leaks the XOR between the fixed secret     and a known plaintext, allowing the disclosure of the     secret text, such as secure HTTPS cookies, and possibly     resulting in the hijacking of an authenticated session.
    (CVE-2016-2183)

  - An unspecified flaw exists in the Security: Encryption     subcomponent that allows an authenticated, remote     attacker to disclose sensitive information.
    (CVE-2016-5584)

  - A flaw exists in the tls_decrypt_ticket() function in     t1_lib.c due to improper handling of ticket HMAC     digests. An unauthenticated, remote attacker can exploit     this, via a ticket that is too short, to crash the     process, resulting in a denial of service.
    (CVE-2016-6302)

  - An integer overflow condition exists in the     MDC2_Update() function in mdc2dgst.c due to improper     validation of user-supplied input. An unauthenticated,     remote attacker can exploit this to cause a heap-based     buffer overflow, resulting in a denial of service     condition or possibly the execution of arbitrary code.
    (CVE-2016-6303)

  - A flaw exists in the ssl_parse_clienthello_tlsext()     function in t1_lib.c due to improper handling of overly     large OCSP Status Request extensions from clients. An     unauthenticated, remote attacker can exploit this, via     large OCSP Status Request extensions, to exhaust memory     resources, resulting in a denial of service condition.
    (CVE-2016-6304)

  - An out-of-bounds read error exists in the certificate     parser that allows an unauthenticated, remote attacker     to cause a denial of service via crafted certificate     operations. (CVE-2016-6306)

  - A flaw exists in the check_log_path() function within     file sql/sys_vars.cc due to inadequate restrictions on     the ability to write to the my.cnf configuration file     and allowing the loading of configuration files from     path locations not used by current versions. An     authenticated, remote attacker can exploit this issue     by using specially crafted queries that utilize logging     functionality to create new files or append custom     content to existing files. This allows the attacker to     gain root privileges by inserting a custom .cnf file     with a 'malloc_lib=' directive pointing to specially     crafted mysql_hookandroot_lib.so file and thereby cause     MySQL to load a malicious library the next time it is     started. (CVE-2016-6662)

  - A flaw exists in wolfSSL, specifically within the C     software version of AES Encryption and Decryption, due     to table lookups not properly considering cache-bank     access times. A local attacker can exploit this, via a     specially crafted application, to disclose AES keys.
    (CVE-2016-7440)

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