Summary
A flaw in the CUDA Optimizer component of OpenPPL ppl.nn allows an attacker to read memory outside its intended bounds by manipulating inputs to the InitQuantization function. The attack can be launched remotely without logging in, but it requires some user action.

Read the original description
A vulnerability has been found in OpenPPL ppl.nn up to bb84dc9952809b3a5a0036858a3d9f68af1c83d5. The affected element is the function OptGraph::InitQuantization of the file src/ppl/nn/engines/cuda/optimizer/opt_graph.cc of the component CUDA Optimizer. Such manipulation of the argument per_channel/bit_width/tensor_max/tensor_min/scale leads to out-of-bounds read. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The project was informed of the problem early through an issue report but has not responded yet.
