The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 326b2f3e-6fc7-4661-955d-a772760db9cf advisory.

  • TensorFlow is an open source platform for machine learning. The reference kernel of the CONV_3D_TRANSPOSE TensorFlow Lite operator wrongly increments the data_ptr when adding the bias to the result. Instead of data_ptr += num_channels; it should be data_ptr += output_num_channels; as if the number of input channels is different than the number of output channels, the wrong result will be returned and a buffer overflow will occur if num_channels > output_num_channels. An attacker can craft a model with a specific number of input channels. It is then possible to write specific values through the bias of the layer outside the bounds of the buffer. This attack only works if the reference kernel resolver is used in the interpreter. We have patched the issue in GitHub commit 72c0bdcb25305b0b36842d746cc61d72658d2941. The fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1, 2.9.3, and TensorFlow 2.8.4, as these are also affected and still in supported range. (CVE-2022-41894)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

  - TensorFlow is an open source platform for machine learning. The reference kernel of the
    `CONV_3D_TRANSPOSE` TensorFlow Lite operator wrongly increments the data_ptr when adding the bias to the
    result. Instead of `data_ptr += num_channels;` it should be `data_ptr += output_num_channels;` as if the
    number of input channels is different than the number of output channels, the wrong result will be
    returned and a buffer overflow will occur if num_channels > output_num_channels. An attacker can craft a
    model with a specific number of input channels. It is then possible to write specific values through the
    bias of the layer outside the bounds of the buffer. This attack only works if the reference kernel
    resolver is used in the interpreter. We have patched the issue in GitHub commit
    72c0bdcb25305b0b36842d746cc61d72658d2941. The fix will be included in TensorFlow 2.11. We will also
