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 released on 16/3/2019, adds protection against fake connection requests and terminal authentication, which are intended to steal the information connection. The new version 0.71 comes after 20 months of inactivity and fixes a total of eight security issues.
Five of them vulnerabilities corrected with PuTTY 0.71 found through the program bounty bug funded by the European Union, and set the amount at € 90,000 as a reward for anyone who reports errors and holes in 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.
Here you can see the list of all fixes made in 0.71. You can download the 0.71 version from here.
