https://notcve.org/view.php?id=CVE-2014-3430
Dovecot 1.1 before 2.2.13 and dovecot-ee before 2.1.7.7 and 2.2.x before 2.2.12.12 does not properly close old connections, which allows remote attackers to cause a denial of service (resource consumption) via an incomplete SSL/TLS handshake for an IMAP/POP3 connection. Dovecot 1.1 anterior a 2.2.13 y dovecot-ee anterior a 2.1.7.7 y 2.2.x anterior a 2.2.12.12 no cierra debidamente conexiones antiguas, lo que permite a atacantes remotos causar una denegación de servicio (consumo de recursos) a través de una negociación SSL/TLS incompleta para una conexión IMAP/POP3. • http://advisories.mageia.org/MGASA-2014-0223.html http://dovecot.org/pipermail/dovecot-news/2014-May/000273.html http://linux.oracle.com/errata/ELSA-2014-0790.html http://permalink.gmane.org/gmane.mail.imap.dovecot/77499 http://rhn.redhat.com/errata/RHSA-2014-0790.html http://secunia.com/advisories/59051 http://secunia.com/advisories/59537 http://secunia.com/advisories/59552 http://www.debian.org/security/2014/dsa-2954 http://www.mandriva.com/security/advisories?name=MDVSA& • CWE-287: Improper Authentication CWE-400: Uncontrolled Resource Consumption •

checkpassword-reply in Dovecot before 2.2.7 performs setuid operations to a user who is authenticating, which allows local users to bypass authentication and access virtual email accounts by attaching to the process and using a restricted file descriptor to modify account information in the response to the dovecot-auth server. checkpassword-reply en Dovecot anteriores a 2.2.7 ejecuta operaciones setuid a usuarios que se están autenticando, lo cual permite a usuarios locales sortear la autenticación y acceder a cuentas de email virtuales adjuntandose al proceso y utilizando un descriptor de fichero restringido para modificar información de la cuenta en la respuesta al servidor dovecot-auth. • http://cpanel.net/tsr-2013-0010-full-disclosure http://secunia.com/advisories/54808 http://wiki2.dovecot.org/AuthDatabase/CheckPassword#Security http://www.dovecot.org/list/dovecot-news/2013-November/000264.html https://usn.ubuntu.com/3556-2 • CWE-287: Improper Authentication •
