"The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has 389-ds-base packages installed that are
affected by a vulnerability:
- In 389-ds-base up to version 1.4.1.2, requests are
handled by workers threads. Each sockets will be waited
by the worker for at most 'ioblocktimeout' seconds.
However this timeout applies only for un-encrypted
requests. Connections using SSL/TLS are not taking this
timeout into account during reads, and may hang
longer.An unauthenticated attacker could repeatedly
create hanging LDAP requests to hang all the workers,
resulting in a Denial of Service. (CVE-2019-3883)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
