Detail

A vulnerability has been discovered and corrected in dovecot:

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 (CVE-2014-3430).

The updated packages have been patched to correct this issue.

Title: RHSA-2014:0790: dovecot security update (Moderate)
Description: Dovecot is an IMAP server, written with security primarily in mind, for Linux and other UNIX-like systems. It also contains a small POP3 server. It supports mail in both the maildir or mbox format. The SQL drivers and authentication plug-ins are provided as subpackages. It was discovered that Dovecot did not properly discard connections trapped in the SSL/TLS handshake phase. A remote attacker could use this flaw to cause a denial of service on an IMAP/POP3 server by exhausting the pool of available connections and preventing further, legitimate connections to the IMAP/POP3 server to be made. (CVE-2014-3430) All dovecot users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the updated packages, the dovecot service will be restarted automatically.
