Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

frp versions 0.53.0 through 0.70.0 are vulnerable to an integer overflow in the frps SSH Tunnel Gateway when it parses SSH exec requests, but only when the gateway is enabled. An unauthenticated remote attacker can crash the whole frps process with a single crafted request. Upgrade to frp 0.70.1, or disable the SSH Tunnel Gateway if you cannot upgrade.
