Hi Jason, I suggest replace `depth:4;` to `http_method;`. Replace it's work on my test. I have another suggest, replace `isdataat:200,relative;` to `isdataat:200,relative; content:!"|0A|"; within:200;`. I have another another suggest, on pcre, replace `(?!\n)` to `(?!\r?\n)`.
I think your suggested changes make a lot of sense, but that wasn't really my point. Why did a "depth:4" rule match *inside* a stream instead of the *beginning* of a stream?
Please upgrade to snort v2.9.0.5.
Is there a stream5 bug in 2.9.0.3 that caused this? Changelog doesn't show anything. My understanding of how snort merges packets into streams is contradicted by this event: either my understanding is incorrect, or there's a bug(?) -- Cheers Jason Haar Information Security Manager, Trimble Navigation Ltd.
