Vulnerability	Vulnerable Version
C Heap-based Buffer Overflow sharp is a High performance Node.js image processing, the fastest module to resize JPEG, PNG, WebP, GIF, AVIF and TIFF images 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

sharp is a High performance Node.js image processing, the fastest module to resize JPEG, PNG, WebP, GIF, AVIF and TIFF images

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.

Remote Code Execution (RCE)

sharp is a High performance Node.js image processing, the fastest module to resize JPEG, PNG, WebP, GIF, AVIF and TIFF images

Affected versions of this package are vulnerable to Remote Code Execution (RCE). There is a possible vulnerability in logic that is run only at npm install time when installing the package. If an attacker has the ability to set the value of the PKG_CONFIG_PATH environment variable in a build environment then they might be able to use this to inject an arbitrary command at npm install time. This is not part of any runtime code and does not affect Windows users at all.
