Ubuntu Security Notice USN-5993-1

samba vulnerabilities
==========================================================================

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

- Ubuntu 22.10
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

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

Software Description:
- samba: SMB/CIFS file, print, and login server for Unix

Details:

Demi Marie Obenour discovered that the Samba LDAP server incorrectly
handled certain confidential attribute values. A remote authenticated
attacker could possibly use this issue to obtain certain sensitive
information. (CVE-2023-0614)

Andrew Bartlett discovered that the Samba AD DC admin tool incorrectly
sent passwords in cleartext. A remote attacker could possibly use this
issue to obtain sensitive information. (CVE-2023-0922)

Update instructions:

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

Ubuntu 22.10:
   samba                           2:4.16.8+dfsg-0ubuntu1.1

Ubuntu 22.04 LTS:
   samba                           2:4.15.13+dfsg-0ubuntu1.1

Ubuntu 20.04 LTS:
   samba                           2:4.15.13+dfsg-0ubuntu0.20.04.2

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