Wireshark bug 11358



The GSM RLC/MAC dissector could go into an infinite loop. Discovered by Antti Levomäki and Christian Jalio.


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.


Upgrade to Wireshark 1.12.7 or later.
