Synopsis

The remote Debian host is missing a security-related update.

Description

Several issues have been identified in Samba, the SMB/CIFS file- and print-server implementation for GNU/Linux.

- CVE-2007-2444 When translating SIDs to/from names using Samba local list of user and group accounts, a logic error in the smbd daemon's internal security stack may result in a transition to the root user id rather than the non-root user. The user is then able to temporarily issue SMB/CIFS protocol operations as the root user. This window of opportunity may allow the attacker to establish addition means of gaining root access to the server.

- CVE-2007-2446 Various bugs in Samba's NDR parsing can allow a user to send specially crafted MS-RPC requests that will overwrite the heap space with user defined data.

- CVE-2007-2447 Unescaped user input parameters are passed as arguments to /bin/sh allowing for remote command execution.

Solution

Upgrade the samba package.

For the stable distribution (etch), these problems have been fixed in version 3.0.24-6etch1.

For the testing and unstable distributions (lenny and sid, respectively), these problems have been fixed in version 3.0.25-1.

How to Run

Here is how to run the Debian DSA-1291-1 : samba - several vulnerabilities as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select Debian Local Security Checks plugin family.
On the right side table select Debian DSA-1291-1 : samba - several vulnerabilities plugin ID 25228.
Specify the target on the Settings tab and click to Save the scan.
Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl debian_DSA-1291.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a debian_DSA-1291.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - debian_DSA-1291.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state debian_DSA-1291.nasl -t <IP/HOST>

Go back to menu.
