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

high Nessus Plugin ID 28060

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.
