Patch Published: 2012-04-10
CVE [?]: CVE-2012-1182
CPE [?]: cpe:/a:samba:samba

Synopsis

The remote Samba server is affected by multiple buffer overflow vulnerabilities.

Description

According to its banner, the version of Samba 3.x running on the remote host is earlier than 3.6.4 / 3.5.14 / 3.4.16. It is, therefore, affected by multiple heap-based buffer overflow vulnerabilities.

An error in the DCE/RPC IDL (PIDL) compiler causes the RPC handling code it generates to contain multiple heap-based buffer overflow vulnerabilities. This generated code can allow a remote, unauthenticated attacker to use malicious RPC calls to crash the application and possibly execute arbitrary code as the root user.

Note that Nessus has not actually tried to exploit this issue or otherwise determine if one of the associated patches has been applied.

Solution

Either install the appropriate patch referenced in the project's advisory or upgrade to 3.6.4 / 3.5.14 / 3.4.16 or later.

How to Run

Here is how to run the Samba 3.x < 3.6.4 / 3.5.14 / 3.4.16 RPC Multiple Buffer Overflows 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 Misc. plugin family.
On the right side table select Samba 3.x < 3.6.4 / 3.5.14 / 3.4.16 RPC Multiple Buffer Overflows plugin ID 58662.
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 samba_rpc_multiple_buffer_overflows.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

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

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

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

Go back to menu.
