Ubuntu 7.04 : samba regression (USN-460-2)

Ubuntu Security Notice (C) 2007-2016 Canonical, Inc. / NASL script (C) 2007-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

USN-460-1 fixed several vulnerabilities in Samba. The upstream changes
for CVE-2007-2444 had an unexpected side-effect in Feisty. Shares
configured with the 'force group' option no longer behaved correctly.
This update corrects the problem. We apologize for the inconvenience.

Paul Griffith and Andrew Hogue discovered that Samba did not fully
drop root privileges while translating SIDs. A remote authenticated
user could issue SMB operations during a small window of opportunity
and gain root privileges. (CVE-2007-2444).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 7.2
(CVSS2#AV:L/AC:L/Au:N/C:C/I:C/A:C)
