Details

Description

The OpenFlow dissector (and possibly others) could go into a long loop. Discovered by Antti Levomäki.

Impact

It may be possible to make Wireshark consume excessive CPU resources by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file.

Resolution

Upgrade to Wireshark 2.0.5, 1.12.13 or later.
