Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound in the stack_reallocate process. An attacker can cause memory corruption or potentially execute arbitrary code by triggering a stack growth beyond approximately 1 GiB, which results in an integer overflow and subsequent use of attacker-controlled offsets in memory operations.
