Description Pedro Sampaio 2023-03-29 15:11:20 UTC

The fix in 4.6.16, 4.7.9, 4.8.4 and 4.9.7 for CVE-2018-10919 Confidential attribute disclosure vi LDAP filters was insufficient and an attacker may be
able to obtain confidential BitLocker recovery keys from a Samba AD DC.

Comment 1 Pedro Sampaio 2023-03-29 15:11:36 UTC

Created samba tracking bugs for this issue:

Affects: fedora-all [bug 2182777]

Comment 2 Sandipan Roy 2023-03-30 05:04:51 UTC

The samba package as shipped with Red Hat Enterprise Linux 6, 7, 8 and 9 and Red Hat Gluster is not affected by this issue as Red Hat doesn't provide the AD domain controller capability with it.
