The SASL authentication functionality in 389 Directory Server before 1.2.11.26 allows remote authenticated users to connect as an arbitrary user and gain privileges via the authzid parameter in a SASL/GSSAPI bind.

It was discovered that the 389 Directory Server did not properly handle certain SASL-based authentication mechanisms. A user able to authenticate to the directory using these SASL mechanisms could connect as any other directory user, including the administrative Directory Manager account. This could allow them to modify configuration values, as well as read and write any data the directory holds.

An important security bug was fixed.
