I have a website hosted on an Amazon AMI Linux instance. 

We had a PCI Scan recently and we failed the scan because we have Apache **2.2.23** installed, and apparently it contains vulnerabilities that have been since fixed on **2.2.24**.

I did a `sudo yum update` but after checking the apache version using `httpd -v` it still reports 2.2.23. A `yum info httpd` also confirms that the repository version is 2.2.23

Is there any way to force yum to update to the latest version or to add a custom repository pointing to the latest apache release? I am a developer and I don't have a lot of experience hosting on linux, so I am a little bit stumped as to what to do. 

Any tips will be appreciated, thanx!
