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 receiverβs WhatsApp contacts.
