Server-side Request Forgery (SSRF)

Overview

golang.org/x/net/http/httpproxy is a package for HTTP proxy determination based on environment variables, as provided by net/http's ProxyFromEnvironment function

Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) in proxy.go, because hostname matching against proxy patterns may treat an IPv6 zone ID as a hostname component. An environment variable value like *.example.com could be matched to a request intended for [::1%25.example.com]:80.

Remediation

Upgrade golang.org/x/net/http/httpproxy to version 0.36.0 or higher.

Allocation of Resources Without Limits or Throttling

Overview

golang.org/x/crypto/ssh is a SSH client and server

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in handshakeTransport in handshake.go. An internal queue gets populated with received packets during the key exchange process, while waiting for the client to send a SSH_MSG_KEXINIT. An attacker can cause the server to become unresponsive to new connections by delaying or withholding this message, or by causing the queue to consume all available memory.

Remediation

Upgrade golang.org/x/crypto/ssh to version 0.35.0 or higher.
