CVE-2018-16858: libreoffice: Arbitrary python functions in arbitrary modules on the filesystem can be executed without warning

Severity: Critical

CVSS Score: 9.8

It was found that libreoffice before versions 6.0.7 and 6.1.3 was vulnerable to a directory traversal attack which could be used to execute arbitrary macros bundled with a document. An attacker could craft a document, which when opened by LibreOffice, would execute a Python method from a script in any arbitrary file system location, specified relative to the LibreOffice install location.
