CVE-2022-23568

Tensorflow is an Open Source Machine Learning Framework. The implementation of AddManySparseToTensorsMap is vulnerable to an integer overflow which results in a CHECK-fail when building new TensorShape objects so, an assert failure based denial of service. We are missing some validation on the...

CVE-2022-21733 Memory exhaustion in Tensorflow

Tensorflow is an Open Source Machine Learning Framework. The implementation of StringNGrams can be used to trigger a denial of service attack by causing an out of memory condition after an integer overflow. We are missing a validation on padwitdh and that result in computing a negative value for...

CVE-2022-21732 Memory exhaustion in Tensorflow

Tensorflow is an Open Source Machine Learning Framework. The implementation of ThreadPoolHandle can be used to trigger a denial of service attack by allocating too much memory. This is because the numthreads argument is only checked to not be negative, but there is no upper bound on its value. Th...

Tensorflow is an Open Source Machine Learning Framework. The implementation of shape inference for ReverseSequence does not fully validate the value of batchdim and can result in a heap OOB read. There is a check to make sure the value of batchdim does not go over the rank of the input, but there...

Tensorflow is an Open Source Machine Learning Framework. The implementation of shape inference for Dequantize is vulnerable to an integer overflow weakness. The axis argument can be -1 the default value for the optional argument or any other positive value at most the number of dimensions of the...

PYSEC-2022-109

Tensorflow is an Open Source Machine Learning Framework. The implementation of FractionalAvgPoolGrad does not consider cases where the input tensors are invalid allowing an attacker to read from outside of bounds of heap. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this...

Name of the Vulnerable Software and Affected Versions: TensorFlow versions prior to 2.8.0 TensorFlow versions 2.7.1, 2.6.3, and 2.5.3 are also affected Description: The implementation of SparseCountSparseOutput in TensorFlow is vulnerable to a heap overflow. This issue can be exploited using the...

GHSA-CQ76-MXRC-VCHH Crash in `tf.math.segment_*` operations

Impact The implementation of tf.math.segment operations results in a CHECK-fail related abort and denial of service if a segment id in segmentids is large. python import tensorflow as tf tf.math.segmentmaxdata=np.ones1,10,1, segmentids=1676240524292489355 tf.math.segmentmindata=np.ones1,10,1,...

GHSA-J86V-P27C-73FM Unitialized access in `EinsumHelper::ParseEquation`

Impact During execution, EinsumHelper::ParseEquation is supposed to set the flags in inputhasellipsis vector and outputhasellipsis boolean to indicate whether there is ellipsis in the corresponding inputs and output. However, the code only changes these flags to true and never assigns false. cc f...

GHSA-5CRJ-C72X-M7GQ Null pointer exception when `Exit` node is not preceded by `Enter` op

Impact The process of building the control flow graph for a TensorFlow model is vulnerable to a null pointer exception when nodes that should be paired are not: python import tensorflow as tf @tf.function def func: return tf.rawops.Exitdata=False,False func This occurs because the code assumes th...

TensorFlow is an open source platform for machine learning. In affected versions the shape inference code for the Cudnn operations in TensorFlow can be tricked into accessing invalid memory, via a heap buffer overflow. This occurs because the ranks of the input, inputh and inputc parameters are n...
