FreeBSD : samba -- incorrect permission checks vulnerability (0fa15e08-92ec-11e1-a94a-00215c6a37bb)

medium Nessus Plugin ID 58937

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The Samba project reports :

Samba versions 3.4.x to 3.6.4 inclusive are affected by a vulnerability that allows arbitrary users to modify privileges on a file server.

Security checks were incorrectly applied to the Local Security Authority (LSA) remote proceedure calls (RPC) CreateAccount, OpenAccount, AddAccountRights and RemoveAccountRights allowing any authenticated user to modify the privileges database.

This is a serious error, as it means that authenticated users can connect to the LSA and grant themselves the 'take ownership' privilege. This privilege is used by the smbd file server to grant the ability to change ownership of a file or directory which means users could take ownership of files or directories they do not own.

Solution

Update the affected packages.
