3 April 2023
ldb could be made to expose sensitive information over the network.
Releases
Packages
- 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
Ubuntu 20.04
After a standard system update you need to restart applications using ldb,
such as Samba, to make all the necessary changes.
