Mremoteng: Update PuTTYNG to 0.71

[JongleurNin]

mRemoteNG currently includes PuTTYNG v0.70, which has known security vulnerabilities.

Expected Behavior

A new mRemoteNG release should be issued that bundles PuTTYNG v0.71. PuTTYNG repo to v0.71

Current Behavior

mRemoteNG includes PuTTYNG v0.70, which has known security vulnerabilities that are documented at https://www.chiark.greenend.org.uk/~sgtatham/putty/changes.html.

Possible Solution

It looks like the separate repo for PuTTYNG is already in the process of being updated, per https://github.com/mRemoteNG/PuTTYNG/commit/31890b846d0e50f6c89b7ee4f68a33bda01ef48a. So the developers already appear to be aware of this, it just hasn't been reported as an issue yet.

Steps to Reproduce (for bugs)

1. Install mRemoteNG 1.76.16.41771.
2. Browse to C:\Program Files (x86)\mRemoteNG.
3. View properties of PuTTYNG.exe and verify that the version is 0.70.

Context

Users want to ensure that they are not using tools with known security vulnerabilities.

Your Environment

Windows 10

[kmscode]

Work has already been completed to merge 0.71 into puttyng. Testing has not yet been completed.

Build is available here if you want to test:
https://ci.appveyor.com/project/mremoteng/puttyng-77pmq/builds/23130281/artifacts

This will be included in 1.77 and we will discuss another 1.76 release.

Thanks for the quick comment! I patched PuTTYNG.exe and verified that the version has been incremented, and that the code is signed by the developer. I also verified that I could SSH into a few Linux machines from Windows with this patch applied.

Getting some scaling problems inside mremoteng after this update..text is cut on the sides.

[sparerd]

@nmat Within all mRemoteNG or just ssh sessions?

[nmat]

Only SSH it seems.

Tested with CentOS and Ubuntu and all of them scale out of the tabbed area

[nmat]

for example on ubuntu top and left side is cut by 1 character

[sparerd]

Hmm I thought we had fixed that. I'll take a look

[kmscode]

@sparerd we fixed that in 1.77... I'll find the code and backport to 1.76. PuTTYNG already has the necessary changes, so I think that's why we're seeing issues in 1.76 - I only tested 0.71 with 1.77.

[sparerd]

Ahh yea that's why... 😢

[sparerd]

I'll create a new issue for this
