Adobe Reader 9.3.1 Lite
If you download Adobe Reader from the official Adobe website you notice (or might not) that the version offered on that website is still version 9.3 of Adobe Reader and not the latest version 9.3.1. Users who do not update the pdf reader after downloading and installing that version make their computer system vulnerable to security exploits that have been fixed in Adobe Reader 9.3.1. A user who for instance downloads the pdf reader to install it offline on another computer system might not know about the update.
It is not clear why Adobe is not updating the version offered for download on their website. That it is possible shows the release of Adobe Reader 9.3.1 Lite which is the – unofficial – lite version of Adobe Reader.
