Samba Exposure of Machine Account Credentials

SECUNIA ADVISORY ID:
SA19455

VERIFY ADVISORY:
http://secunia.com/advisories/19455/

CRITICAL:
Less critical

IMPACT:
Exposure of sensitive information

WHERE:
Local system

SOFTWARE:
Samba 3.x
http://secunia.com/product/2999/

DESCRIPTION:
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.

SOLUTION:
Update to version 3.0.22 or apply patch.

Patch for version 3.0.21[a-c]:
http://us1.samba.org/samba/ftp/patches/security/samba-3.0.21-CAN-2006-1059.patch

PROVIDED AND/OR DISCOVERED BY:
