CVE-2016-2522: Wireshark

Medium severity, CVSS 5.9. EPSS: 2.1% chance of exploitation in the next 30 days.

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.

Affected products
