New version of the popular PuTTy program that hopefully arrived at the 0.71 number and fixes bugs that allowed for false login requests.
The latest version of it PuTTY SSH and Telnet client which was released on 16-3-2019, adds protection against fake connection requests and terminal authentication that are designed to steal login information. The new 0.71 version comes after 20 months of inactivity and fixes eight security issues altogether.
Five of the vulnerabilities corrected with PuTTY 0.71 were found through the program bounty bug funded by the European Union, and had set the amount of € 90,000 as a reward for anyone reporting bugs and holes in the software with its twenty-year history on the internet.
However, PuTTY 0.71 fixes one serious overflow error which exists in all previous versions of the client program. Another significant weakness mentioned (through the European Union's reward program) is that of hijacking the help file (.CHM format) in the PuTTY variant for Windows.
