| Vetor | AV:N/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
PuTTY versions prior to 0.71
Description
The issue is related to insufficient input validation in the cryptographic protection mechanism of PuTTY. This can be exploited by a remote attacker to cause a denial-of-service. Multiple denial-of-service attacks can be triggered by writing to the terminal.
Recommendations
For PuTTY versions prior to 0.71, update to version 0.71 or later to resolve the issue. As a temporary workaround, consider restricting access to the terminal to minimize the risk of exploitation.
