> DESCRIPTION:
> Some vulnerabilities have been reported in Samba, which can be
> exploited by malicious users to perform certain actions with
> escalated privileges and to compromise a vulnerable system, and by
> malicious people to compromise a vulnerable system.
>
> 1) An error in smbd when translating SIDs to and from names can be
> exploited to issue SMB/CIFS protocol operations as the root user.
>
> Successful exploitation requires a valid user session.
>
> 2) Errors in NDR parsing can be exploited to cause heap based buffer
> overflows via specially crafted MS-RPC requests.
>
> Successful exploitation allows execution of arbitrary code, but
> requires a valid user session.
>
> 3) An input validation error when updating a user's password can be
> exploited to inject and execute arbitrary shell commands via a
> specially crafted MS-RPC call.
>
> Successful exploitation of this vulnerability requires that the
> "username map script" option is set in smb.conf, which is not the
> default setting. In addition, to successfully exploit this
> vulnerability via remote printer and file share management, an
> attacker requires a valid user session.
>
> Vulnerability #1 is reported in versions 3.0.23d through 3.0.25pre2.
> Vulnerabilities #2 and #3 are reported in versions 3.0.0 through
