Summary

The image rendering component (createGenericPreview) of the Open Whisper Signal app through 2.29.0 for iOS fails to check for unreasonably large images before manipulating received images. This allows for a large image sent to a user to exhaust all available memory when the image is displayed, resulting in a forced restart of the device.
