Vulnerability in the MySQL Connectors component of Oracle MySQL (subcomponent: Connector/C). Supported versions that are affected are 6.1.10 and earlier. Difficult to exploit vulnerability allows low privileged attacker with network access via multiple protocols to compromise MySQL Connectors. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Connectors. Note: The documentation has also been updated for the correct way to use mysql_stmt_close(). • http://www.debian.org/security/2017/dsa-3922 http://www.oracle.com/technetwork/security-advisory/cpujul2017-3236622.html http://www.securityfocus.com/bid/99730 http://www.securitytracker.com/id/1038928 •
CVSS: 5.9EPSS: 0%CPEs: 27EXPL: 1CVE-2015-3152 – mysql: use of SSL/TLS can not be enforced in mysql client library (oCERT-2015-003, BACKRONYM)
https://notcve.org/view.php?id=CVE-2015-3152
Oracle MySQL before 5.7.3, Oracle MySQL Connector/C (aka libmysqlclient) before 6.1.3, and MariaDB before 5.5.44 use the --ssl option to mean that SSL is optional, which allows man-in-the-middle attackers to spoof servers via a cleartext-downgrade attack, aka a "BACKRONYM" attack. Oracle MySQL en versiones anteriores a 5.7.3, Oracle MySQL Connector/C (también conocido como libmysqlclient) en versiones anteriores a 6.1.3 y MariaDB en versiones anteriores a 5.5.44 utiliza la opción --ssl significa que SSL es opcional, lo que permite a atacantes man-in-the-middle suplantar servidores a través de un ataque de degradación de texto plano, también conocida como un ataque "BACKRONYM". It was found that the MySQL client library permitted but did not require a client to use SSL/TLS when establishing a secure connection to a MySQL server using the "--ssl" option. A man-in-the-middle attacker could use this flaw to strip the SSL/TLS protection from a connection between a client and a server. • http://lists.fedoraproject.org/pipermail/package-announce/2015-July/161436.html http://lists.fedoraproject.org/pipermail/package-announce/2015-July/161625.html http://mysqlblog.fivefarmers.com/2014/04/02/redefining-ssl-option http://mysqlblog.fivefarmers.com/2015/04/29/ssltls-in-5-6-and-5-5-ocert-advisory http://packetstormsecurity.com/files/131688/MySQL-SSL-TLS-Downgrade.html http://rhn.redhat.com/errata/RHSA-2015-1646.html http://rhn.redhat.com/errata/RHSA-2015-1647.html http://rhn& • CWE-295: Improper Certificate Validation •
