| Class: VULNERABILITY | Family: windows |
The host is installed with PuTTY before 0.63 and is prone to buffer overflow vulnerability. The flaw is present in the application, which is not properly handled during computation of a modular inverse and triggers the overflow during a division by zero by the bignum functionality. Successful exploitation allows remote SSH servers to cause a denial of service (crash).
