Suricata 4.1 released!

After a longer than intended release development cycle, the OISF development team is proud to present Suricata 4.1.

Main new features are inclusion of the protocols SMBv1/2/3, NFSv4, Kerberos, FTP, DHCP, IKEv2. All of them have been implemented in Rust to ensure their introduction will not be compromising to the security and the stability of the complete system.

Support for tracking and logging TLS 1.3 has been added, including JA3 support.

On performance side, one of the main improvements is the availability of capture bypass for AF_PACKET implemented on top of the new eXpress Data Path (XDP) capability of Linux kernel. Windows users will benefit from the 4.1 release with a new IPS mode based on WinDivert.

All new protocols require Rust so Suricata 4.1 is not really 4.1 if you don’t have Rust. This is why the build system is now enabling Rust by default if it is available on the build machine.

This is the first release where Suricata-Update 1.0, the new Suricata rule updater, is bundled.

Suricata 2.0.8 Available!

The OISF development team is pleased to announce Suricata 2.0.8. This release fixes a number of important 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.

A number of other issues were fixed. Upgrading is highly recommended.

Suricata 2.0.7 Available!

Photo by Eric Leblond

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.

  • Bug #1385: DCERPC traffic parsing issue
  • Bug #1391: http uri parsing issue
  • Bug #1383: tcp midstream window issue
  • Bug #1318: A thread-sync issue in streamTCP
  • Bug #1375: Regressions in list keywords option
  • Bug #1387: pcap-file hangs on systems w/o atomics support
  • Bug #1395: dump-counters unix socket command failure
  • Optimization #1376: file list is not cleaned up
