Overview
Affected versions of this package are vulnerable to Out-of-bounds Write in the SASL UNBIND process. An attacker can exhaust server resources by sending specially crafted requests that cause connections to stall, potentially leading to service disruption for legitimate users.
Workaround
This vulnerability can be mitigated by restricting network access to the service to only trusted clients and networks using firewall rules to limit inbound connections to the LDAP ports (typically 389 for LDAP and 636 for LDAPS) to known, authorized IP addresses or subnets.
