Описание
A flaw was found in the Samba AD LDAP server. The AD DC database audit logging module can access LDAP message values freed by a preceding database module, resulting in a use-after-free issue. This issue is only possible when modifying certain privileged attributes, such as userAccountControl.
Отчет
Although versions of Samba shipped with Red Hat Enterprise Linux do not support Samba in AD mode, the affected code is shipped in RHEL with the libldb package.
Меры по смягчению последствий
Disabling the AD DC database audit logging prevents the use-after-free from occurring, as that is the only component that will access the original message.
