Title
Out-of-bounds reads during instruction decoding in pybddisasm
Summary
Out-of-bounds read vulnerabilities in the pybddisasm Python bindings may disclose adjacent process memory during instruction decoding. The nd_decode function may read up to 15 bytes without checking the actual length of the supplied Python buffer. The nd_decode_ex, nd_decode_ex2, and nd_decode_with_context functions pass the caller-supplied buffer size to the decoder without validating it against the actual length of the Python buffer. Data read beyond the buffer may be exposed through nd_get_instrux_bytes, which returns a fixed-length list of 16 bytes. Exploitation requires an application to invoke the affected APIs with a short buffer or an oversized length and to expose the resulting bytes to an attacker. The pybddisasm package is no longer maintained.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
