FKIE_CVE-2015-8720

Vulnerability from fkie_nvd - Published: 2016-01-04 05:59 - Updated: 2026-06-17 00:35
Severity
5.5 (Medium) - CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H
Summary
The dissect_ber_GeneralizedTime function in epan/dissectors/packet-ber.c in the BER dissector in Wireshark 1.12.x before 1.12.9 and 2.0.x before 2.0.1 improperly checks an sscanf return value, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.
