Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

PuTTY是软件开发者Simon Tatham所研发的一套免费的Telnet、Rlogin和SSH客户端软件。WinSCP是捷克布拉格经济大学所开发与维护的一套使用SSH的开源图形化SFTP和FTP客户端。 PuTTY 0.62及之前版本，WinSCP 5.1.6之前的版本，以及其它产品中存在整数溢出漏洞。通过在SSH握手期间向RSA密钥签名中加入一个负值，触发基于堆的缓冲区溢出，远程SSH服务器端的攻击者可利用该漏洞造成拒绝服务（崩溃），并有可能在运行PuTTY的程序上执行任意代码。

N/A
Source: CVE Program / CVE List V5
Vulnerability Description
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.
