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

psi/zdevice2.c in Artifex Ghostscript before 9.26 allows remote attackers to bypass intended access restrictions because available stack space is not checked when the device remains the same.
