Description Huzaifa S. Sidhpurwala 2012-10-03 05:24:16 UTC

Wireshark failed to properly assign data-type for some data field parsed via the PPP dissector. 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.
