What is CVE-2019-3883?

In 389-ds-base prior to version 1.4.1.2, a Denial of Service vulnerability exists due to improper handling of requests. Worker threads wait for a specific timeout for unencrypted requests, while SSL/TLS connections are not subjected to this timeout, allowing attackers to create malicious LDAP requests. These requests can hang indefinitely, effectively consuming all worker threads and preventing legitimate requests from being processed, leading to disruption of services.

Affected Version(s)

389-ds-base affects up to 1.4.1.2
