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 •

https://notcve.org/view.php?id=CVE-2015-1779
The VNC websocket frame decoder in QEMU allows remote attackers to cause a denial of service (memory and CPU consumption) via a large (1) websocket payload or (2) HTTP headers section. El decodificador de frames websocket VNC en QEMU permite a atacantes remotos causar una denegación de servicio (consumo de CPU y memoria) a través de una gran (1) carga útil websocket o (2) sección de cabeceras HTTP It was found that the QEMU's websocket frame decoder processed incoming frames without limiting resources used to process the header and the payload. An attacker able to access a guest's VNC console could use this flaw to trigger a denial of service on the host by exhausting all available memory and CPU. • http://lists.fedoraproject.org/pipermail/package-announce/2015-April/154656.html http://lists.fedoraproject.org/pipermail/package-announce/2015-April/155196.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00033.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00042.html http://rhn.redhat.com/errata/RHSA-2015-1931.html http://rhn.redhat.com/errata/RHSA-2015-1943.html http://www.debian.org/security/2015/dsa-3259 http://www.openwall.com/lists/oss-secu • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
