Debian DLA-1779-1 : 389-ds-base security update

high Nessus Plugin ID 124658

Synopsis

The remote Debian host is missing a security update.

Description

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
