Workarounds
ADP: To mitigate this denial of service vulnerability, restrict network access to any service that utilizes the `golang.org/x/crypto/ssh` library and is exposed to untrusted networks. Implement firewall rules to allow connections only from trusted hosts or networks. This action limits the ability of malicious peers to send unsolicited global request responses. A restart of the affected service may be necessary for the new network rules to be applied effectively.
There are currently no legacy QID mappings associated with this CVE.
