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

An issue was discovered in vcSetXCutTextProc() in VNConsole.c in LinuxVNC and VNCommand from the LibVNC/vncterm distribution through 0.9.10. Missing sanitization of the client-specified message length may cause integer overflow or possibly have unspecified other impact via a specially crafted VNC packet.
