Software Update: PuTTY 0.67 Beta

A new release of PuTTY has become available and as usual it is offered as beta. PuTTY is one of the most popular telnet and ssh clients, which makes it possible to remotely manage a computer over a secure connection. Originally, the program was only available for Windows, but now there are also clients for the various Unix platforms. The changelog for version 0.67 can be found below.

These features are new in beta 0.67

• Security fix: a buffer overrun in the old-style SCP protocol when receiving the header of each file downloaded from the server is fixed. see vuln-pscp-sink-sscanf.
• Windows PuTTY now sets its process ACL more restrictively, in an attempt to defend against malicious other processes reading sensitive data out of its memory.
• Assorted other robustness fixes for crashes and memory leaks.
• We have started using Authenticode to sign our Windows executables and installer.
