You forgot to include this (from the link above):

*Solution/Vendor Information/Workaround:*

PuTTY 0.55 fixes these vulnerabilities. It is available at: 
http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html 

PuTTY maintainers recommend that everybody upgrade to 0.55 as soon as 
possible.

The latest PuTTY version in ports is 0.55.
