Exploitability
| CWE ID | Description |
|---|---|
| CWE-190 | The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is an integer overflow in the kiss_fft_alloc() function of KissFFT versions before a specific fix. On 32-bit platforms, the nfft parameter is not properly validated before being used in a size calculation, which can cause the calculation to wrap around to a smaller value. This leads to malloc() allocating a buffer that is too small, and then a loop writes more data than the buffer can hold, causing a heap buffer overflow.
How can this vulnerability impact me? :
The heap buffer overflow caused by this vulnerability can lead to memory corruption, which may result in crashes, data corruption, or potentially allow an attacker to execute arbitrary code with the privileges of the affected application. This can compromise system stability and security on 32-bit architectures using vulnerable KissFFT versions.
