This is only exploitable if the color_cache_bits value defines which size to use.UPII Spring 2008 Course Guide Part II: Magnetism and Optics Dr. The OOB write to the undersized array happens in ReplicateValue. When BuildHuffmanTable() attempts to fill the second-level tables it may write data out-of-bounds. libwebp allows codes that are up to 15-bit ( MAX_ALLOWED_CODE_LENGTH). ![]() The kTableSize array only takes into account sizes for 8-bit first-level table lookups but not second-level table lookups. The color_cache_bits value defines which size to use. An attacker can craft a special WebP lossless file that triggers the ReadHuffmanCodes() function to allocate the HuffmanCode buffer with a size that comes from an array of precomputed sizes: kTableSize. Electron is a framework which lets you write cross-platform desktop applications using JavaScript, HTML and CSS.Īffected versions of this package are vulnerable to Heap-based Buffer Overflow when the ReadHuffmanCodes() function is used. ![]()
