The OISF development team is pleased to announce Suricata 2.0.7. This
release fixes a number of 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.
