I typically update all my software fairly regularly. I noticed a while ago that I have an old version of Adobe Acrobat Reader even after doing the updates many times. I finally I decided to uninstall Adobe Acrobat Reader 8.something so I could install the latest version.
I was reminded that I need to do this when I went to the Secunia web site and saw the latest Adobe Acrobat Reader advisory - which unfortunately includes version 9:
Adobe Acrobat Reader - Memory Corruption Vulnerability
This particular vulnerability above is only confirmed for Linux but chances are it occurs on other operating systems as well.
Interestingly enough, after uninstalling Adobe Acrobat Reader version 8, I try to go to the Adobe web site and when I click the link to install the most recent version of Adobe I got an error saying my IP was blocked. Ok so I'll just jump on a different network. That IP was blocked too. Ok that's odd. I went to a completely different machine and was able to click the download link. So I came back to document all of this in my blog - and suddenly now I can download again.
One thing I don't like about Adobe's web site is that the download is in HTTP, not HTTPS. How do we know files and bits and bytes aren't getting altered in transit?
