Mô tả CVE
P-Net before 1.0.3 contains an integer underflow in pf_cpm_c_data_ind(). When handling a received cyclic data frame while the consumer is in the FRUN or RUN state, the offset of the APDU status was computed as the frame length minus 4 using 16-bit arithmetic, without checking that the frame is long enough. A crafted short frame makes the offset wrap around, so the function reads outside the receive buffer. This can cause a crash (denial of service) or disclose memory content.
Thông tin CVE
Điểm yếu liên quan
| Tên điểm yếu | Nguồn | |
|---|---|---|
| Out-of-bounds Read The product reads data past the end, or before the beginning, of the intended buffer. |
||
| Integer Underflow (Wrap or Wraparound) The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result. |
