Description
This is 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.
It was brought to our attention by the Yahoo Pentest Team.

The DCERPC parsing issue has CVE-2015-0928 assigned to it.
Workaround: disable the parser as follows:
In your suricata.yaml go down to the 'app-layer' section and change 'enabled' to 'no' under 'dcerpc', like so:
app-layer:
protocols:
tls:
enabled: yes
detection-ports:
dp: 443
#no-reassemble: yes
dcerpc:
enabled: no
After this, restart Suricata.
