Ubuntu Security Notice USN-5992-1
April 03, 2023

ldb vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

ldb could be made to expose sensitive information over the network.

Software Description:
- ldb: LDAP-like embedded database

Details:

Demi Marie Obenour discovered that ldb, when used with Samba, incorrectly
handled certain confidential attribute values. A remote authenticated
attacker could possibly use this issue to obtain certain sensitive
information.

Update instructions:

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

Ubuntu 22.04 LTS:
   libldb2                         2:2.4.4-0ubuntu0.22.04.2

Ubuntu 20.04 LTS:
   libldb2                         2:2.4.4-0ubuntu0.20.04.2

After a standard system update you need to restart applications using ldb,
such as Samba, to make all the necessary changes.
