Description

OISF Development Team reports :

The OISF development team is pleased to announce Suricata 2.0.8. This release fixes a number of issues in the 2.0 series.

The most important issue is a bug in the DER parser which is used to decode SSL/TLS certificates could crash Suricata. This issue was reported by Kostya Kortchinsky of the Google Security Team and was fixed by Pierre Chifflier of ANSSI.

Those processing large numbers of (untrusted) pcap files need to update as a malformed pcap could crash Suricata. Again, credits go to Kostya Kortchinsky.
