This is only exploitable if the color_cache_bits value defines which size to use. 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. You can do this by setting BC to 1 when calling. libwebp allows codes that are up to 15-bit ( MAX_ALLOWED_CODE_LENGTH). Figure 2.9 or if using a Mac, click on the green button in the upper left corner). Prior to installation, ensure that sufficient free temp space (. 154 Xenon has a minimum alveolar concentration (MAC) of 72 at age 40, making it 44 more potent than N 2 O as an anesthetic. While neither anesthetic nor antinociceptive, this reduces anesthesia-emergent nausea and vomiting. The kTableSize array only takes into account sizes for 8-bit first-level table lookups but not second-level table lookups. NOTE: Download and install patch for Bug 21160684 if installing this release of the OFS AAAI. Xenon is a competitive inhibitor of the serotonin 5-HT 3 receptor. 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.
