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

epan/reassemble.c in TShark in Wireshark 2.0.x before 2.0.3 relies on incorrect special-case handling of truncated Tvb data structures, which allows remote attackers to cause a denial of service (use-after-free and application crash) via a crafted packet.
