libwebp.so is vulnerable to Out Of Bounds Memory Write. The vulnerability is due to the BuildHuffmanTable function in src/dec/vp8l_dec.c improperly allocating memory to the table when parsing a stream, which results in an application crash or Arbitrary Code Execution when reading a webp image file.
