New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

The dissect_nhdr_extopt function in epan/dissectors/packet-lbmc.c in the LBMC dissector in Wireshark 2.0.x before 2.0.2 does not validate length values, which allows remote attackers to cause a denial of service (stack-based buffer overflow and application crash) via a crafted packet.
