Name of the Vulnerable Software and Affected Versions libvips versions prior to 8.18.2

Description The tiffload operation can incorrectly determine the number of channels in a JPEG or JPEG2000-encoded tile within a TIFF image, which may lead to a buffer overflow. A buffer overflow occurs when a program writes more data to a block of memory than it can hold, potentially corrupting memory or allowing arbitrary code execution.
