8Subject: [PATCH 3/3] ftp,imap,pop3,smtp: reject STARTTLS server response
9 pipelining
10
11If a server pipelines future responses within the STARTTLS response, the
12former are preserved in the pingpong cache across TLS negotiation and
13used as responses to the encrypted commands.
14
15This fix detects pipelined STARTTLS responses and rejects them with an
16error.
