Description Huzaifa S. Sidhpurwala 2011-09-13 05:15:57 UTC
A large loop in the OpenSafety dissector could cause a crash. It may be possible to make Wireshark crash by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file. This affects versions 1.6.0 to 1.6.1 and has been fixed in version 1.6.2
