-Subject: [PATCH] Fix integer overflow in gdImageWebpCtx
-
-Integer overflow can be happened in expression gdImageSX(im) * 4 *
-gdImageSY(im). It could lead to heap buffer overflow in the following
-code. This issue has been reported to the PHP Bug Tracking System. The
-proof-of-concept file will be supplied some days later. This issue was
-discovered by Ke Liu of Tencent's Xuanwu LAB.

-Subject: [PATCH] Fix #492: 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).
