Severity: 3-Major


If there is a truncated BIG-IP software image in /shared/images, a kernel lockup and reboot could occur. One way to have a truncated image in /shared/images is by using iControl/SOAP to upload the image. Using SOAP, the image is uploaded in chunks, so until the last chunk is uploaded, the image is not complete/is truncated.


Traffic disruption caused by the reboot.


-- Truncated BIG-IP image in /shared/images -- Using SOAP to upload the image.


If you are using SOAP to upload BIG-IP software images, upload them to /shared first and then move them to /shared/images.
