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 bytes_repr_len function in Wireshark 1.4.5 uses an incorrect pointer argument, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via arbitrary TCP traffic.
