Vulnerability Information

Synopsis

The remote Mandrake Linux host is missing one or more security updates.

Description

A number of vulnerabilities have been found in the Linux 2.2 kernel that have been addressed with the latest 2.2.25 release.

A bug in the kernel module loader code could allow a local user to gain root privileges. This is done by a local user using ptrace and attaching to a modprobe process that is spawned if the user triggers the loading of a kernel module.

A temporary workaround can be used to defend against this flaw. It is possible to temporarily disable the kmod kernel module loading subsystem in the kernel after all of the required kernel modules have been loaded. Be sure that you do not need to load additional kernel modules after implementing this workaround. To use it, as root execute :

echo /no/such/file >/proc/sys/kernel/modprobe

To automate this, you may wish to add it as the last line of the /etc/rc.d/rc.local file. You can revert this change by replacing the content '/sbin/modprobe' in the /proc/sys/kernel/modprobe file. The root user can still manually load kernel modules with this workaround in place.

As well, multiple ethernet device drivers do not pad frames with null bytes, which could allow remote attackers to obtain information from previous packets or kernel memory by using malformed packets.

Finally, the 2.2 kernel allows local users to cause a crash of the host system by using the mmap() function with a PROT_READ parameter to access non-readable memory pages through the /proc/pid/mem interface.

All users are encouraged to upgrade to the latest kernel version provided.

Solution

Update the affected packages.

How to Run

Here is how to run the Mandrake Linux Security Advisory : kernel22 (MDKSA-2003:039) 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 Mandriva Local Security Checks plugin family.
On the right side table select Mandrake Linux Security Advisory : kernel22 (MDKSA-2003:039) plugin ID 14023.
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 mandrake_MDKSA-2003-039.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a mandrake_MDKSA-2003-039.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - mandrake_MDKSA-2003-039.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 mandrake_MDKSA-2003-039.nasl -t <IP/HOST>

Go back to menu.
