Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound due to unchecked arithmetic in the internal buffer_len function. An attacker can cause memory corruption and potentially execute arbitrary code by triggering an integer overflow that results in an undersized heap allocation, leading to out-of-bounds memory access through safe API calls such as set, push, or reserve.
