Doc Text:
A flaw was found in the golang.org/x/image/tiff component. This vulnerability allows a remote attacker to cause a denial of service (DoS) by providing a specially crafted, invalid TIFF image. When the TIFF decoder attempts to process an image with an out-of-bounds strip offset, it can panic, leading to the unavailability of the affected system.
