Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound due to a 32-bit integer overflow in the AES-GCM implementation's length counters. An attacker can compromise the integrity of authenticated data by processing payloads or Additional Authenticated Data (AAD) exceeding 512 megabytes, resulting in incorrect authentication tag computation.
