Description
+ Version v0.0.0-20211202192323-5770296d904e of golang.org/x/crypto fixes a vulnerability in the golang.org/x/crypto/ssh package which allowed unauthenticated clients to cause a panic in SSH servers. When using AES-GCM or ChaCha20Poly1305, consuming a malformed packet which contains empty plaintext causes a panic, due to the assumption that there will always be at least one byte, containing the number of padding bytes.
