Technical details
The flat file database driver in Apache OpenOffice versions through 4.1.16 fails to properly restrict file access when processing crafted documents, allowing unauthenticated local file read. An attacker must convince a user to open a malicious document, after which the driver automatically reads arbitrary files without user interaction or consent. The vulnerability affects the database backend component responsible for flat file database operations.
