![]() ![]() This is only exploitable if the color_cache_bits value defines which size to use. See what's possible with Electron 64 bit with sample cod. The OOB write to the undersized array happens in ReplicateValue. Compatible with Mac, Windows, and Linux, Electron apps build and run on three platforms.The API Demos app interactively demonstrates the most important features of the Electron API. 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.
