Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the compressed-token decoder process. An attacker can access sensitive memory contents, including environment variables, passwords, heap and stack data, and library memory pointers, by sending specially crafted data to trigger an integer overflow that causes the process to read and return data from outside the intended buffer bounds.
