libpng versions before 1.6.55 contain an out-of-bounds read vulnerability in png_set_quantize(). When called without a histogram and with a palette containing more than twice the maximum number of colors supported by the user's display, certain palettes cause an infinite loop that reads beyond an internal heap-allocated buffer. PNG images conforming to the specification can trigger the flaw. The vulnerability can disrupt applications performing the affected palette quantization and is fixed in libpng 1.6.55.
