Subject: [CVE-2020-13958] Apache OpenOffice - Unrestricted actions leads to
 arbitrary code execution in crafted documents

CVE-2020-13958 Unrestricted actions leads to arbitrary code execution in crafted documents

Fixed in Apache OpenOffice 4.1.8


A vulnerability in Apache OpenOffice scripting events allows an attacker to construct 
documents containing hyperlinks pointing to an executable on the target users file system.
These hyperlinks can be triggered unconditionally. In fixed versions no internal protocol 
may be called from the document event handler and other hyperlinks require a control-click.

Severity: Low

There are no known exploits of this vulnerability.
A proof-of-concept demonstration exists.

Vendor: The Apache Software Foundation

Versions Affected

Apache OpenOffice 4.0.0, 4.0.1, 4.1.0, 4.1.1, 4.1.2, 4.1.3, 4.1.4, 4.1.5, 4.1.6, and 4.1.7 versions may also be affected.


Install Apache OpenOffice 4.1.8 for the latest maintenance and cumulative security fixes.
