To make clear - the bug results in DoS-like behaviour for sensor, which quickly exhausts own resources and locks up completely in result.
I "like" how Cisco kept it quiet for 4 months since I reported it (and they reproduced it in own lab) arguing it's not a bug. Finally published with status "fixed", when the actual fixed release for FTD is only coming "some time" in 2019...
Sad to see largest and used-to-be most impactful network vendor rolling down to shady shop. Sigh.
