vulnerable Apache version 2.2.3
ClearOS contains backported fixes for Apache 2.2.3. Other items listed do not affect Apache on Linux, are not vulnerabilities on this version or have been deemed not risks.
Reports that ClearOS are affected by this vulnerability are grossly inaccurate and represent an inability for the audit system to properly distinguish Apache running on Windows from Apache running on Linux. Additionally, the inability to detect backported patches causes many items to appear vulnerable when in fact they have been fixed typically at or near the release of the original CVE.
Run updates to ensure that you are up to date.
Additionally, ensure that only trusted admins have access to the command line of your servers that are running Apache.
