CVE-2016-2522  (opens in a new tab)
CWE-119  (opens in a new tab)

How to fix?

Upgrade Alpine:3.3 wireshark to version 2.0.2-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream wireshark package and not the wireshark package as distributed by Alpine. See How to fix? for Alpine:3.3 relevant fixed versions and status.

The dissect_ber_constrained_bitstring function in epan/dissectors/packet-ber.c in the ASN.1 BER dissector in Wireshark 2.0.x before 2.0.2 does not verify that a certain length is nonzero, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted packet.
