TensorFlow is an end-to-end open source platform for machine learning. An attacker can trigger a denial of service via a CHECK-fail in tf.rawops.AddManySparseToTensorsMap. This is because the...

CVE-2021-29617

TensorFlow is an end-to-end open source platform for machine learning. An attacker can cause a denial of service via CHECK-fail in tf.strings.substr with invalid arguments. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3,...

CVE-2021-29561 CHECK-fail in `LoadAndRemapMatrix`

TensorFlow is an end-to-end open source platform for machine learning. An attacker can cause a denial of service by exploiting a CHECK-failure coming from tf.rawops.LoadAndRemapMatrix. This is because the...

CVE-2021-29575 Overflow/denial of service in `tf.raw_ops.ReverseSequence`

TensorFlow is an end-to-end open source platform for machine learning. The implementation of tf.rawops.ReverseSequence allows for stack overflow and/or CHECK-fail based denial of service. The...

CVE-2021-29531

CVE-2021-29531 affects TensorFlow and relates to a denial-of-service risk in PNG encoding when an attacker supplies an empty input tensor for pixel data. The issue stems from encode_png_op.cc validating only total pixel count and passing image data to png::WriteImageToBuffer, which calls CHECK_NO...

CVE-2021-29543

CVE-2021-29543 affects TensorFlow’s CTCGreedyDecoder with a CHECK_LT invariant in tf.raw_ops.CTCGreedyDecoder that can trigger a denial-of-service via abnormal termination. Connected sources provide concrete technical details: the issue resides in TensorFlow core/kernels/ctc_decoder_ops.cc lines ...

CVE-2021-29544

TensorFlow vulnerability CVE-2021-29544 (QuantizeAndDequantizeV4Grad) is triggered by a rank-validation CHECK-fail in tf.raw_ops.QuantizeAndDequantizeV4Grad, caused by inputs not being validated before passing to QuantizeAndDequantizePerChannelGradientImpl. The issue leads to denial of service vi...

CVE-2021-29545

CVE-2021-29545 concerns TensorFlow and describes a heap-based out-of-bounds issue in SparseTensorToCSRSparseMatrix caused by a double redirection when accessing csr_row_ptr via indices(i, 0) + 1. This can lead to a denial of service by writing outside heap data. The connected OSV/GHSA entries con...
