Synopsis

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

Description

Recently multiple servers of the Debian project were compromised using a Debian developers account and an unknown root exploit. Forensics revealed a burneye encrypted exploit. Robert van der Meulen managed to decrypt the binary which revealed a kernel exploit. Study of the exploit by the Red Hat and SuSE kernel and security teams quickly revealed that the exploit used an integer overflow in the brk system call. Using this bug it is possible for a userland program to trick the kernel into giving access to the full kernel address space. This problem was found in September by Andrew Morton, but unfortunately that was too late for the 2.4.22 kernel release.

This bug has been fixed in kernel version 2.4.23 for the 2.4 tree and 2.6.0-test6 kernel tree. For Debian it has been fixed in version 2.4.18-14 of the kernel source packages, version 2.4.18-12 of the i386 kernel images and version 2.4.18-11 of the alpha kernel images.

Solution

Upgrade the affected kernel-image-2.4.18-1-alpha, kernel-image-2.4.18-1-i386, and kernel-source-2.4.18 packages.

How to Run

Here is how to run the Debian DSA-403-1 : kernel-image-2.4.18-1-alpha, kernel-image-2.4.18-1-i386, kernel-source-2.4.18 - local root exploit 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-403-1 : kernel-image-2.4.18-1-alpha, kernel-image-2.4.18-1-i386, kernel-source-2.4.18 - local root exploit plugin ID 15240.
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-403.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a debian_DSA-403.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-403.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-403.nasl -t <IP/HOST>

Go back to menu.
