Description
An issue when unzipping docx, pptx, and xlsx documents in WhatsApp for iOS prior to v2.20.61 and WhatsApp Business for iOS prior to v2.20.61 could have resulted in an out-of-memory denial of service. This issue would have required the receiver to explicitly open the attachment if it was received from a number not in the receiver's WhatsApp contacts.
