Suricata 2.0.7 Available!
The OISF development team is pleased to announce Suricata 2.0.7. This release fixes a number of important issues in the 2.0 series.
Two major issues. The first was brought to our attention by the Yahoo Pentest Team. It’s a parsing issue in the DCERPC parser that can happen when Suricata runs out of memory. The exact scope of the problem isn’t clear, but it could certainly lead to crashes. RCE might theoretically be possible but looks like it’s very hard.
The second issue was reported by Darien Huss of Emerging Threats. This is technically a libhtp issue, but it affects Suricata detection and logging. Certain characters in the URI could confuse the parsing of the HTTP request line, leading to possible detection bypass for ‘http_uri’ and to incomplete logging of the URI. Libhtp 0.5.17 has been released to address this and is bundled in 2.0.7.
Other than that a bunch of improvements and fixes. It should work again on CentOS 5. Midstream TCP was improved and some performance optimizations for HTTP proxy traffic were made.
Upgrading is highly recommended.
