BIT-TENSORFLOW-2022-41894 Buffer overflow in `CONV_3D_TRANSPOSE` on TFLite

TensorFlow is an open source platform for machine learning. The reference kernel of the CONV3DTRANSPOSE TensorFlow Lite operator wrongly increments the dataptr when adding the bias to the result. Instead of dataptr += numchannels; it should be dataptr += outputnumchannels; as if the number of inp...

BIT-TENSORFLOW-2022-41895 `MirrorPadGrad` heap out of bounds read in Tensorflow

TensorFlow is an open source platform for machine learning. If MirrorPadGrad is given outsize input paddings, TensorFlow will give a heap OOB error. We have patched the issue in GitHub commit 717ca98d8c3bba348ff62281fdf38dcb5ea1ec92. The fix will be included in TensorFlow 2.11. We will also...

BIT-TENSORFLOW-2022-41902 Out of bounds write in grappler in Tensorflow

TensorFlow is an open source platform for machine learning. The function MakeGrapplerFunctionItem takes arguments that determine the sizes of inputs and outputs. If the inputs given are greater than or equal to the sizes of the outputs, an out-of-bounds memory read or a crash is triggered. We hav...

CBL Mariner 2.0 Security Update: tensorflow (CVE-2022-41893)

The version of tensorflow installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-41893 advisory. - TensorFlow is an open source platform for machine learning. If tf.rawops.TensorListResize is given a...

CVE-2022-41910

TensorFlow is an open source platform for machine learning. The function MakeGrapplerFunctionItem takes arguments that determine the sizes of inputs and outputs. If the inputs given are greater than or equal to the sizes of the outputs, an out-of-bounds memory read or a crash is triggered. We hav...

Tensorflow vulnerable to Out-of-Bounds Read

Impact When the BaseCandidateSamplerOp function receives a value in trueclasses larger than rangemax, a heap oob vuln occurs. python tf.rawops.ThreadUnsafeUnigramCandidateSampler trueclasses=0x100000,1, numtrue = 2, numsampled = 2, unique = False, rangemax = 2, seed = 2, seed2 = 2 Patches We have...

`CHECK` fail in `BCast` overflow

Impact If BCast::ToShape is given input larger than an int32, it will crash, despite being supposed to handle up to an int64. An example can be seen in tf.experimental.numpy.outer by passing in large input to the input b. python import tensorflow as tf value = tf.constantshape=2, 1024, 1024, 1024...

CVE-2022-41897

TensorFlow is an open source platform for machine learning. If FractionMaxPoolGrad is given outsize inputs rowpoolingsequence and colpoolingsequence, TensorFlow will crash. We have patched the issue in GitHub commit d71090c3e5ca325bdf4b02eb236cfb3ee823e927. The fix will be included in TensorFlow...

CVE-2022-41891

TensorFlow is an open source platform for machine learning. If tf.rawops.TensorListConcat is given elementshape=, it results segmentation fault which can be used to trigger a denial of service attack. We have patched the issue in GitHub commit fc33f3dc4c14051a83eec6535b608abe1d355fde. The fix wil...

CVE-2022-41888

TensorFlow is an open source platform for machine learning. When running on GPU, tf.image.generateboundingboxproposals receives a scores input that must be of rank 4 but is not checked. We have patched the issue in GitHub commit cf35502463a88ca7185a99daa7031df60b3c1c98. The fix will be included i...

CVE-2022-41885

TensorFlow is an open source platform for machine learning. When tf.rawops.FusedResizeAndPadConv2D is given a large tensor shape, it overflows. We have patched the issue in GitHub commit d66e1d568275e6a2947de97dca7a102a211e01ce. The fix will be included in TensorFlow 2.11. We will also cherrypick...

CVE-2022-41890 `CHECK` fail in `BCast` overflow in Tensorflow

TensorFlow is an open source platform for machine learning. If BCast::ToShape is given input larger than an int32, it will crash, despite being supposed to handle up to an int64. An example can be seen in tf.experimental.numpy.outer by passing in large input to the input b. We have patched the...

CVE-2022-41909 Segfault in `CompositeTensorVariantToComponents` in Tensorflow

TensorFlow is an open source platform for machine learning. An input encoded that is not a valid CompositeTensorVariant tensor will trigger a segfault in tf.rawops.CompositeTensorVariantToComponents. We have patched the issue in GitHub commits bf594d08d377dc6a3354d9fdb494b32d45f91971 and...

CVE-2022-41911 Invalid char to bool conversion when printing a tensor in Tensorflow

TensorFlow is an open source platform for machine learning. When printing a tensor, we get it's data as a const char array since that's the underlying storage and then we typecast it to the element type. However, conversions from char to bool are undefined if the char is not 0 or 1, so...

CVE-2022-41889 Segfault via invalid attributes in `pywrap_tfe_src.cc` in Tensorflow

TensorFlow is an open source platform for machine learning. If a list of quantized tensors is assigned to an attribute, the pywrap code fails to parse the tensor and returns a nullptr, which is not caught. An example can be seen in tf.compat.v1.extractvolumepatches by passing in quantized tensors...
