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

Integer underflow in Brotli, as used in Mozilla Firefox before 45.0, allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow) via crafted data with brotli compression.
