Hi, Vendor: The Apache Software Foundation
Versions affected: all versions prior to version 3.15 Apache POI in versions prior to release 3.15 allows remote attackers to cause a denial of service (CPU consumption) via a specially crafted OOXML file, aka an XML Entity Expansion (XEE) attack. Users with applications which accept content from external or untrusted sources are advised to upgrade to Apache POI 3.15 or newer. Thanks to Xiaolong Zhu and Huijun Chen from Huawei Technologies Co., Ltd. for reporting the vulnerability. Dominik Stadler on behalf of the Apache POI PMC
