Vulnerability	Vulnerable Version
C Heap-based Buffer Overflow opencv-python-headless is a Wrapper package for OpenCV python bindings. Affected versions of this package are vulnerable to Heap-based Buffer Overflow when the `ReadHuffmanCodes()` function is used. 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`. The `color_cache_bits` value defines which size to use. The `kTableSize` array only takes into account sizes for 8-bit first-level table lookups but not second-level table lookups. libwebp allows codes that are up to 15-bit (`MAX_ALLOWED_CODE_LENGTH`). When BuildHuffmanTable() attempts to fill the second-level tables it may write data out-of-bounds. The OOB write to the undersized array happens in ReplicateValue. Notes: This is only exploitable if the `color_cache_bits` value defines which size to use.

Heap-based Buffer Overflow

opencv-python-headless is a Wrapper package for OpenCV python bindings.

Affected versions of this package are vulnerable to Heap-based Buffer Overflow when the ReadHuffmanCodes() function is used.
