Description Andrej Nemec 2018-12-04 09:56:51 UTC

In Wireshark 2.6.0 to 2.6.4 and 2.4.0 to 2.4.10, the IxVeriWave file parser could crash. This was addressed in wiretap/vwr.c by adjusting a buffer boundary.

Used AV:L as wiretap library is used for reading capture files, rather than packet capture.
