CVE-2017-15130

Name of the Vulnerable Software and Affected Versions: dovecot versions prior to 2.2.34

Description: A denial of service flaw was found in the TLS SNI configuration lookups of the Dovecot mail server. An attacker able to generate random SNI server names could exploit this issue, leading to excessive memory usage and causing the process to restart. The vulnerability is related to an error in the TLS protocol implementation configuration.

Recommendations: For versions prior to 2.2.34, update to version 2.2.34 or later to resolve the issue. As a temporary workaround, consider restricting access to the TLS SNI configuration to minimize the risk of exploitation.
