Integer overflow in PuTTY 0.62 and earlier, WinSCP before 5.1.6, and other products that use PuTTY allows remote SSH servers to cause a denial of service (crash) and possibly execute arbitrary code in certain applications that use PuTTY via a negative size value in an RSA key signature during the SSH handshake, which triggers a heap-based buffer overflow.

CVE-2013-4206 CVE-2013-4207 CVE-2013-4208 CVE-2013-4852 putty: Integer overflow, leading to heap-based buffer overflow during SSH handshake
An integer overflow, leading to heap-based buffer overflow flaw was found in the way DSS and RSA implementation of PuTTY, a SSH, telnet, and rlogin client, used to process certain SSH handshake messages. A rogue SSH server could issue a specially-crafted SSH handshake message that, when processed in PuTTY client would lead to client crash or, potentially, arbitrary code execution with the privileges of the user running the client.
