Description Dhananjay Arunesh 2019-02-28 13:20:28 UTC
In Wireshark 2.4.0 to 2.4.12 and 2.6.0 to 2.6.6, the RPCAP dissector could crash. This was addressed in epan/dissectors/packet-rpcap.c by avoiding an attempted dereference of a NULL conversation.

Hrm. Seems like this was introduced via https://code.wireshark.org/review/gitweb?p=wireshark.git;a=commitdiff;h=d58a3ffe4f69366f25fd192e41a89b4769c7d22c

That's a fairly recent commit and contradicts the versions upstream claims to be affected.

Yes this seems to be the case.
