It was discovered that the emergency logging system in 389-ds-base (the 389 Directory Server) is affected by a race condition caused by the invalidation of the concurrently used log file file descriptor without proper locking. This issue might be triggered by remote attackers to cause DoS (crash) and any other undefined behavior.
For Debian 8 ‘Jessie’, this problem has been fixed in version 1.3.3.5-4+deb8u3.
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.
