+From 5770296d904e90f15f38f77dfc2e43fdf5efc083 Mon Sep 17 00:00:00 2001
+From: Roland Shoemaker <roland@golang.org>

+Subject: [PATCH] ssh: don't assume packet plaintext size
+
+When reading GCM and ChaChaPoly1305 packets, don't make assumptions
+about the size of the enciphered plaintext. This fixes two panics
+caused by standards non-compliant malformed packets.
+
+Thanks to Rod Hynes, Psiphon Inc. for reporting this issue.
+
+Fixes golang/go#49932
+Fixes CVE-2021-43565
