Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound in the WebCrypto cipher output length calculation in src/crypto/crypto_aes.cc, where data_len + blockSize + tag_len is computed as a signed int before being passed to OpenSSL. An attacker can abort the process and cause a denial of service by passing an input around a multiple of 2 GiB to subtle.encrypt(), which overflows that length computation and crashes the runtime.
