Subject: [PATCH] Imagecolormatch Out Of Bounds Write on Heap
At least some of the image reading functions may return images which
use color indexes greater than or equal to im->colorsTotal. We cater
to this by always using a buffer size which is sufficient for
`gdMaxColors` in `gdImageColorMatch()`.
Resolves: #1678104

From d98e5a2ace46adcefa093c029663575fd677bf05 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Potential double-free in gdImage*Ptr()
Whenever `gdImage*Ptr()` calls `gdImage*Ctx()` and the latter fails, we
must not call `gdDPExtractData()`; otherwise a double-free would
happen. Since `gdImage*Ctx()` are void functions, and we can't change
that for BC reasons, we're introducing static helpers which are used
internally.
We're adding a regression test for `gdImageJpegPtr()`, but not for
`gdImageGifPtr()` and `gdImageWbmpPtr()` since we don't know how to
trigger failure of the respective `gdImage*Ctx()` calls.
This potential security issue has been reported by Solmaz Salimi (aka.
Rooney).
