Samba LSA RPC `take ownership´ Privilege Security Bypass Vulnerability

A vulnerability has been identified in Samba, which can be exploited by malicious users to bypass certain security restrictions.

The security issue is caused due to improper application of security checks in the CreateAccount, OpenAccount, AddAccountRights, and RemoveAccountRights remote procedure calls (RPC) within the Local Security Authoriy (LSA). This can be exploited to gain "take ownership" privileges and e.g. change the ownership of arbitrary files and directories on the smdb file server.
