- Fix array bounds checking in BinPAC: for arrays that are
fields within a record, the bounds check was based on a pointer
to the start of the record rather than the start of the array
field, potentially resulting in a buffer over-read.
- Fix SMTP command string comparisons: the number of bytes
compared was based on the user-supplied string length and can
lead to incorrect matches. e.g. giving a command of "X"
incorrectly matched "X-ANONYMOUSTLS" (and an empty commands
match anything).
- Weird" events are now generally suppressed/sampled by default
according to some tunable parameters.
- Improved handling of empty lines in several text protocol
analyzers that can cause performance issues when seen in long
sequences.
- Add `smtp_excessive_pending_cmds' weird which serves as a
notification for when the "pending command" queue has reached
an upper limit and been cleared to prevent one from attempting
to slowly exhaust memory.
