| 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 0.73
Description
The issue is related to accessing freed memory locations, which could allow remote SSH-1 servers to cause a denial of service. This can be achieved via an SSH1 MSG DISCONNECT message. The estimated number of potentially affected devices worldwide is not available. There is no information about real-world incidents where this issue was exploited.
Recommendations
For versions prior to 0.73, update to version 0.73 or later to resolve the issue. As a temporary workaround, consider restricting access to SSH-1 servers to minimize the risk of exploitation. Avoid using the
SSH1 MSG DISCONNECT message in the affected API endpoint until the issue is resolved.Correção
