Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated samba packages that fix several security flaws are now available.

This update has been rated as having critical security impact by the Red Hat Security Response Team.

Samba provides file and printer sharing services to SMB/CIFS clients.

Various bugs were found in NDR parsing, used to decode MS-RPC requests in Samba. A remote attacker could have sent carefully crafted requests causing a heap overflow, which may have led to the ability to execute arbitrary code on the server. (CVE-2007-2446)

Unescaped user input parameters were being passed as arguments to /bin/sh. A remote, authenticated, user could have triggered this flaw and executed arbitrary code on the server. Additionally, on Red Hat Enterprise Linux 5 only, this flaw could be triggered by a remote unauthenticated user if Samba was configured to use the non-default 'username map script' option. (CVE-2007-2447)

Users of Samba should upgrade to these packages, which contain backported patches to correct these issues. After upgrading, Samba should be restarted using 'service smb restart'

On Red Hat Enterprise Linux 5 the impact of these issues is reduced as Samba is constrained by the default SELinux 'targeted' policy.

Red Hat would like to thank the Samba developers, TippingPoint, and iDefense for reporting these issues.

Solution

Update the affected samba packages.

How to Run

Here is how to run the CentOS 3 / 4 / 5 : samba (CESA-2007:0354) 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 CentOS Local Security Checks plugin family.
On the right side table select CentOS 3 / 4 / 5 : samba (CESA-2007:0354) plugin ID 25224.
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 centos_RHSA-2007-0354.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a centos_RHSA-2007-0354.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - centos_RHSA-2007-0354.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 centos_RHSA-2007-0354.nasl -t <IP/HOST>

Go back to menu.
