  1. draw: add fast paths for RGBA64Image 

    Go 1.17 added image.RGBA64Image and draw.RGBA64Image interfaces which
use color.RGBA64 instead of color.Color in order to avoid heap
allocations on pixel operations. Fast paths were added to image/draw
for drawing with these images, but not to x/image/draw. This CL
adds them.

Fixes golang/go#62423

goos: windows
goarch: amd64
pkg: golang.org/x/image/draw

  1. go.mod: update go directive to 1.18 

    There's no reason for this module to still be assuming the semantics
of Go 1.12. Pick 1.18 as a semi-arbitrary newer version because it's
used by a few other golang.org/x modules, and it's enough to get the
nice new features like module graph pruning, removed // +build lines,
and so on. See https://go.dev/ref/mod#go-mod-file-go.

Done with:

go get go@1.18
go mod tidy
go fix ./...

Using go1.21.1.

  2. draw: merge draw_go117.go into draw.go 

    This can be done as Go 1.21 and 1.20 are the supported
versions by now, and Go 1.16 is long since unsupported.

  1. draw: simplify some calls to fmt.Fprintf 

    The implementation generator passes the same arguments many times to
some calls to fmt.Fprintf. Use %[n]s notation for these instead. The
generated program does not change.

  1. webp: disallow multiple VP8X chunks 

    Per the spec, there should only be one. A malformed image containing
multiple VP8X chunks can cause unexpected memory usage, since
DecodeConfig will only parse the first chunk, which contains the canvas
size, but a subsequent chunk can indicate a significantly larger canvas,
which we will then try to allocate a buffer for.

  1. tiff: Validate palette indices when parsing palette-color images 

    The existing implementation will succeed to parse a corrupt or malicious
image with color indices out of range of the actual palette, which will
eventually result in a panic when the consumer tries to read the color
at any corrupted pixel.

This issue was originally discovered and filed against a downstream
library: disintegration/imaging#165. This is
also referenced in https://osv.dev/vulnerability/GHSA-q7pp-wcgr-pffx.

Fixes golang/go#67624
