Doc Type: If docs needed, set a value
Doc Text:
It was found that libreoffice 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.

Description Pedro Sampaio 2018-11-14 15:50:45 UTC
A flaw was found in libreoffice. If a document does not contain macros/scripts, but references a pre-installed macro/script execution of those macros/scripts, execution is allowed without warning bypassing normal behavior.

Comment 2 Huzaifa S. Sidhpurwala 2018-11-21 09:47:44 UTC
In versions of libreoffice shipped with Red Hat Enterprise Linux 6 and 7, arbitrary arguements cannot be passed to the scripts/macros, hence meaningful exploitation is difficult.
