## Description

The pcapng\_read\_if\_descr\_block function in wiretap/pcapng.c in the pcapng
parser in Wireshark 1.12.x before 1.12.8 uses too many levels of pointer
indirection, which allows remote attackers to cause a denial of service
(incorrect free and application crash) via a crafted packet that triggers
interface-filter copying.
