## Description

An issue was discovered in Anti-Grain Geometry (AGG) 2.4 as used in SVG++
(aka svgpp) 1.2.3. A heap-based buffer overflow bug in svgpp\_agg\_render may
lead to code execution. In the render\_scanlines\_aa\_solid function, the
blend\_hline function is called repeatedly multiple times. blend\_hline is
equivalent to a loop containing write operations. Each call writes a piece
of heap data, and multiple calls overwrite the data in the heap.
