> A security issue has been reported in Samba, which can be exploited
> by malicious, local users to gain knowledge of sensitive
> information.
> 
> The winbindd daemon saves the machine trust account credentials to
> the world-readable winbind log files in clear text. This may expose
> the credentials, which can be used to impersonate the server in a
> domain and gain additional information.
> 
> Successful exploitation requires that log level is set to 5 or
> above.
> 
> The security issue has been reported in versions 3.0.21 through
> 3.0.21c.
