| summary: Resource exhaustion in github.com/pires/go-proxyproto |
| description: |- |
| The PROXY protocol server does not impose a timeout on reading the header from |
| new connections, allowing a malicious client to cause resource exhaustion and a |
| denial of service by opening many connections and sending no data on them. |
| |
| v0.6.0 of the proxyproto package adds support for a user-defined header timeout. |
| v0.6.1 adds a default timeout of 200ms and v0.6.2 increases the default timeout |
| to 10s. |
