Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound in the kiss_fft_alloc() function when the nfft parameter is not properly validated before being used in a size calculation. An attacker can cause a heap buffer overflow by supplying a large value for nfft on 32-bit architectures, leading to memory corruption and potential code execution.
