    Summary: Memory Exposure in tunnel-agent

    Details: Versions of `tunnel-agent` before 0.6.0 are vulnerable to memory exposure. This is exploitable if user supplied input is provided to the auth value and is a number. Proof-of-concept: ```js require('request')({ method: 'GET', uri: 'http://www.example.com', tunnel: true, proxy:{ protocol: 'http:', host:'127.0.0.1', port:8080, auth:USERSUPPLIEDINPUT // number } }); ``` ## Recommendation Update to version 0.6.0 or later.
