Philippe Antoine	a8079dc978	mqtt: limits the number of active transactions per flow ... Ticket: 4530 So, that we do not get DOS by quadratic complexity, while looking for a new pkt_id over the ever growing list of active transactions	3 years ago

Philippe Antoine	df2cbd6517	http2: event for variable-length integer overflow ... http2_parse_var_uint can overflow the variable-length integer it is decoding. In this case, it now returns an error of kind LengthValue. The new function http2_parse_headers_blocks, which factorizes the code loop for headers, push promise, and continuation, will check for this specific error, and instead of erroring itself, will return the list of so far parsed headers, plus another one with HTTP2HeaderDecodeStatus::HTTP2HeaderDecodeIntegerOverflow This status is then checked by process_headers to create an app-layer event.	3 years ago
Philippe Antoine	334b1382e0	http: : fix int warnings ... Explicitly truncate file names to UINT16_MAX Before, they got implicitly truncated, meaning a UINT16_MAX + 1 file name, went to 0 file name (because of modulo 65536)	3 years ago

Philippe Antoine	6cb6225b28	tcp: rejects FIN+SYN packets as invalid ... Ticket: #4569 If a FIN+SYN packet is sent, the destination may keep the connection alive instead of starting to close it. In this case, a later SYN packet will be ignored by the destination. Previously, Suricata considered this a session reuse, and thus used the sequence number of the last SYN packet, instead of using the one of the live connection, leading to evasion. This commit errors on FIN+SYN so that they do not get processed as regular FIN packets.	3 years ago

Philippe Antoine	e82416a415	http/range: reassemble files from different flows with range ... adds a container, ie a thread safe hash table whose key is the filename keep a tree of unordered ranges, up to a memcap limit adds HTPFileOpenWithRange to handle like HTPFileOpen if there is a range : open 2 files, one for the whole reassembled, and one only for the current range	3 years ago

Jason Ish	8bd68478a4	rules/mqtt: renumber mqtt events to avoid conflict with ssh ... Both SSH and MQTT events were in the 2228000 range. As SSH was added first, renumber MQTT events into the 2229000 range which is free.	4 years ago
Philippe Antoine	caa7946888	smb: adds file overlap event against evasions ... Evasion scenario is - a first dummy write of one byte at offset 0 is done - the second full write of EICAR at offset 0 is then done and does not trigger detection The last write had the final value, and as we cannot "cancel" the previous write, we set an event which is then transformed into an app-layer decoder alert	4 years ago

Victor Julien	631ee383bb	flow/stream: 'wrong thread' as stream event & counter ... Set event at most once per flow, for the first 'wrong' packet. Add 'tcp.pkt_on_wrong_thread' counter.

Victor Julien	843d0b7a10	stream: support RST getting lost/ignored ... In case of a valid RST on a SYN, the state is switched to 'TCP_CLOSED'. However, the target of the RST may not have received it, or may not have accepted it. Also, the RST may have been injected, so the supposed sender may not actually be aware of the RST that was sent in it's name. In this case the previous behavior was to switch the state to CLOSED and accept no further TCP updates or stream reassembly. This patch changes this. It still switches the state to CLOSED, as this is by far the most likely to be correct. However, it will reconsider the state if the receiver continues to talk. To do this on each state change the previous state will be recorded in TcpSession::pstate. If a non-RST packet is received after a RST, this TcpSession::pstate is used to try to continue the conversation. If the (supposed) sender of the RST is also continueing the conversation as normal, it's highly likely it didn't send the RST. In this case a stream event is generated.
