Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound in the D2U macro when processing number literals with a large digit count. An attacker can cause arbitrary stack memory to be overwritten by supplying specially crafted input that triggers a signed integer overflow, leading to a wild stack write with attacker-controlled data.
