A flaw was found in LibreOffice. A remote attacker could exploit this out-of-bounds write vulnerability by tricking a user into opening a specially crafted OOXML (Office Open XML) document with mismatched encryption salt parameters. This could lead to a denial of service (DoS), making the application unavailable, and potentially result in limited information disclosure or integrity impact.
