Name of the Vulnerable Software and Affected Versions Foxit Software's PDF Reader version 9.1.0.5096

Description The issue is related to the handling of certain XFA element attributes, which can lead to an out-of-bounds read when a specially crafted PDF document is opened. This can result in the disclosure of sensitive memory content, potentially aiding in exploitation when combined with another issue.
