Update from upstream with multiple security issues fixed.

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

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.

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

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

  - 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)

  - 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-2016-2178)

  - 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-2016-2179)

  - 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-2016-2180)

  - 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-2016-2181)

  - 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-2016-2182)

  - 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-2016-6302)

  - 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-2016-6304)

  - 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.(CVE-2016-6306)
