DESCRIPTION:
Some security issues have been reported in Suricata, which can be
exploited by malicious people to bypass certain security features.

The security issues are caused due to errors in the processing of
certain TCP packets, which can be exploited to bypass detection rules
by e.g. sending specially crafted packets.

The security issues are reported in versions prior to 1.0.2.

SOLUTION:
Update to version 1.0.2.
