CVE-2016-6803

Status: ModifiedHigh (7.8)—

An installer defect known as an "unquoted Windows search path vulnerability" affected the Apache OpenOffice before 4.1.3 installers for Windows. The PC must have previously been infected by a Trojan Horse application (or user) running with administrative privilege. Any installer with the unquoted search path vulnerability becomes a delayed trigger for the exploit.

CVSS
