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

In Wireshark 2.2.0 to 2.2.6 and 2.0.0 to 2.0.12, the DNS dissector could go into an infinite loop. This was addressed in epan/dissectors/packet-dns.c by trying to detect self-referencing pointers.
