![]() ![]() These lap splices also must be located away from the ends of the column where spalling of the concrete shell surrounding the transverse reinforcement is likely to occur due to a seismic event (ACI 318 Section 18.7.4.3). The type of lap splice that must be used depends on the stress in the longitudinal bars due to the factored load combinations (see ACI 318 Section 10.7.5.2).įor columns that are part of special moment frames in buildings assigned to SDC D, E, or F, lap splices must be tension lap splices and located within the center half of the column length. Similar tables can be created for other tie bar sizes and circular longitudinal bar arrangements.įor columns in ordinary moment frames in buildings assigned to Seismic Design Category (SDC) A or B, or in intermediate moment frames in buildings assigned to SDC C, lap splices of the longitudinal bars are permitted to occur immediately above the top of the slab, which is the preferred location for ease of construction ( Figure 2). The column face dimensions have been rounded to the nearest inch. To facilitate the selection of the longitudinal bars, Table 2 contains the minimum face dimension of rectangular tied columns with normal lap splices based on the minimum spacing requirements assuming 1.5-inch clear cover to #4 ties. ![]() Minimum face dimension (inches) of rectangular tied columns with normal lap splices. This is only exploitable if the color_cache_bits value defines which size to use.Table 2. 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. ![]()
