Note: Versions mentioned in the description apply only to the upstream libpcap package and not the libpcap package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

sf-pcapng.c in libpcap before 1.9.1 does not properly validate the PHB header length before allocating memory.
