Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
In Wireshark 2.6.0 to 2.6.3, the CoAP dissector could crash. This was addressed in epan/dissectors/packet-coap.c by ensuring that the piv length is correctly computed.
