Package : 389-ds-base
Version : 1.3.3.5-4+deb8u6
CVE ID : CVE-2019-3883
Debian Bug : 927939
In 389-ds-base up to version 1.4.1.2, 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
1.3.3.5-4+deb8u6.
We recommend that you upgrade your 389-ds-base packages.
