Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The Apache Web server contains a security vulnerability which can be used to launch a denial of service (DoS) attack or, in some cases, allow remote code execution.

Versions of the Apache Web server up to and including 1.3.24 contain a bug in the routines which deal with requests using 'chunked' encoding. A carefully crafted invalid request can cause an Apache child process to call the memcpy() function in a way that will write past the end of its buffer, corrupting the stack. On some platforms this can be remotely exploited -- allowing arbitrary code to be run on the server.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2002-0392 to this issue.

All users of Apache should update to these errata packages to correct this security issue.

Solution

Update the affected apache, apache-devel and / or apache-manual packages.

How to Run

Here is how to run the RHEL 2.1 : apache (RHSA-2002:126) 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 Red Hat Local Security Checks plugin family.
On the right side table select RHEL 2.1 : apache (RHSA-2002:126) plugin ID 12305.
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 redhat-RHSA-2002-126.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a redhat-RHSA-2002-126.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - redhat-RHSA-2002-126.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 redhat-RHSA-2002-126.nasl -t <IP/HOST>

Go back to menu.
