CWE-20  (opens in a new tab)

How to fix?

Upgrade wireshark to version 1.12.8 or higher.

Overview

Affected versions of this package are vulnerable to Improper Input Validation. 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.
