Package : 389-ds-base Version : 220.127.116.11-4+deb8u6 CVE ID : CVE-2019-3883 Debian Bug : 927939
In 389-ds-base up to version 18.104.22.168, requests were handled by worker threads. Each socket had been waited for by the worker for at most 'ioblocktimeout' seconds. However, this timeout applied only to un-encrypted requests. Connections using SSL/TLS were not taking this timeout into account during reads, and may have hung longer. An unauthenticated attacker could have repeatedly created hanging LDAP requests to hang all the workers, resulting in a Denial of Service.
For Debian 8 "Jessie", this problem has been fixed in version 22.214.171.124-4+deb8u6.
We recommend that you upgrade your 389-ds-base packages.
