+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.
