CVSS: 8.8EPSS: 0%CPEs: 4EXPL: 0CVE-2020-13249 – mariadb-connector-c: Improper validation of content in a OK packet received from server
https://notcve.org/view.php?id=CVE-2020-13249
libmariadb/mariadb_lib.c in MariaDB Connector/C before 3.1.8 does not properly validate the content of an OK packet received from a server. NOTE: although mariadb_lib.c was originally based on code shipped for MySQL, this issue does not affect any MySQL components supported by Oracle. La biblioteca libmariadb/mariadb_lib.c en MariaDB Connector/C versiones anteriores a 3.1.8 no comprueba apropiadamente el contenido de un paquete OK recibido desde un servidor. NOTA: aunque mariadb_lib.c se basó originalmente en el código enviado para MySQL, este problema no afecta a ningún componente de MySQL soportado por Oracle. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00054.html https://github.com/mariadb-corporation/mariadb-connector-c/commit/2759b87d72926b7c9b5426437a7c8dd15ff57945 https://github.com/mariadb-corporation/mariadb-connector-c/compare/v3.1.7...v3.1.8 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UW2ED32VEUHXFN2J3YQE27JIBV4SC2PI https://lists.fedoraproject.org/archives/list/package-announce%40lis • CWE-20: Improper Input Validation •
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 •
