USN-5424-1: OpenLDAP vulnerability

17 May 2022

OpenLDAP could be made to perform arbitrary modifications to the database.



  • openldap - Lightweight Directory Access Protocol


It was discovered that OpenLDAP incorrectly handled certain SQL statements
within LDAP queries in the experimental back-sql backend. A remote attacker
could possibly use this issue to perform an SQL injection attack and alter
the database.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 22.04
Ubuntu 21.10
Ubuntu 20.04
Ubuntu 18.04

In general, a standard system update will make all the necessary changes.
