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

Race condition in a certain Red Hat patch to the PRNG lock implementation in the ssleay_rand_bytes function in OpenSSL, as distributed in openssl-1.0.1e-25.el7 in Red Hat Enterprise Linux (RHEL) 7 and other products, allows remote attackers to cause a denial of service (application crash) by establishing many TLS sessions to a multithreaded server, leading to use of a negative value for a certain length field.
