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

Mozilla Firefox before 42.0, when NTLM v1 is enabled for HTTP authentication, allows remote attackers to obtain sensitive hostname information by constructing a crafted web site that sends an NTLM request and reads the Workstation field of an NTLM type 3 message.
