+Subject: [PATCH] gsocks4aproxy: Fix a single byte buffer overflow in connect
+ messages
+
+`SOCKS4_CONN_MSG_LEN` failed to account for the length of the final nul
+byte in the connect message, which is an addition in SOCKSv4a vs
+SOCKSv4.
+
+This means that the buffer for building and transmitting the connect
+message could be overflowed if the username and hostname are both
+`SOCKS4_MAX_LEN` (255) bytes long.
+
+Proxy configurations are normally statically configured, so the username
+is very unlikely to be near its maximum length, and hence this overflow
+is unlikely to be triggered in practice.
+
+(Commit message by Philip Withnall, diagnosis and fix by Michael
+Catanzaro.)
+
+Fixes: #3461
