Synopsis

The remote host is missing a vendor-supplied security patch

Description

The remote host is missing the patch for the advisory SuSE-SA:2003:049 (Linux Kernel).

This security update fixes a serious vulnerability in the Linux kernel. A missing bounds check in the brk() system call allowed processes to request memory beyond the maximum size allowed for tasks, causing kernel memory to be mapped into the process' address space. This allowed local attackers to obtain super user privileges.

An exploit for this vulnerability is circulating in the wild, and has been used to compromise OpenSource development servers.

There is no temporary workaround for this bug.

This update also fixes several other security issues in the kernel

- race condition with files opened via O_DIRECT which could be exploited to read disk blocks randomly. This could include blocks of previously deleted files with sensitive content. - don't allow users to send signals to kmod - when reading the RTC, don't leak kernel stack data to user space

How to Run

Here is how to run the SuSE-SA:2003:049: Linux Kernel 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 SuSE Local Security Checks plugin family.
On the right side table select SuSE-SA:2003:049: Linux Kernel plugin ID 13817.
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 suse_SA_2003_049.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a suse_SA_2003_049.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - suse_SA_2003_049.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 suse_SA_2003_049.nasl -t <IP/HOST>

Go back to menu.
