**Name of the Vulnerable Software and Affected Versions** OpenLDAP versions prior to 2.4.57 **Description** The issue is related to an assertion failure during syntactic analysis in the OpenLDAP implementation, which can be exploited by a remote attacker to cause a denial of service (DoS) by sending a specially crafted request to slapd. The vulnerability is associated with the X.509 DN parsing in decode.c ber next element. **Recommendations** For versions prior to 2.4.57, update to version 2.4.57 or later to resolve the issue. As a temporary workaround, consider restricting access to the slapd service to minimize the risk of exploitation.
