No detailed vulnerability details are currently availab...

CVE-2021-41221

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...

CVE-2021-41216

TensorFlow is an open source platform for machine learning. In affected versions the shape inference function for Transpose is vulnerable to a heap buffer overflow. This occurs whenever perm contains negative elements. The shape inference function does not validate that the indices in perm are al...

CVE-2021-41213

TensorFlow is an open source platform for machine learning. In affected versions the code behind tf.function API can be made to deadlock when two tf.function decorated Python functions are mutually recursive. This occurs due to using a non-reentrant Lock Python object. Loading any model which...

Stack overflow

TensorFlow is an open source platform for machine learning. In affected versions TensorFlow's Grappler optimizer has a use of unitialized variable. If the trainnodes vector obtained from the saved model that gets optimized does not contain a Dequeue node, then dequeuenode is left unitialized. The...

Code injection

TensorFlow is an open source platform for machine learning. In affected versions TensorFlow's savedmodelcli tool is vulnerable to a code injection as it calls eval on user supplied strings. This can be used by attackers to run arbitrary code on the plaform where the CLI tool runs. However, given...

PYSEC-2021-629

TensorFlow is an open source platform for machine learning. In affected versions the async implementation of CollectiveReduceV2 suffers from a memory leak and a use after free. This occurs due to the asynchronous computation and the fact that objects that have been std::moved from are still...

PYSEC-2021-622

TensorFlow is an open source platform for machine learning. In affected versions the code behind tf.function API can be made to deadlock when two tf.function decorated Python functions are mutually recursive. This occurs due to using a non-reentrant Lock Python object. Loading any model which...

CVE-2021-41227 Arbitrary memory read in `ImmutableConst`

TensorFlow is an open source platform for machine learning. In affected versions the ImmutableConst operation in TensorFlow can be tricked into reading arbitrary memory contents. This is because the tstring TensorFlow string class has a special case for memory mapped strings but the operation...

CVE-2021-41225

CVE-2021-41225 affects TensorFlow’s Grappler optimizer: if train_nodes lacks a Dequeue node, dequeue_node remains uninitialized due to an uninitialized variable in the Grappler code. The documented fix is included in TensorFlow 2.7.0, with cherry-picks for 2.6.1, 2.5.2, and 2.4.4 (still in suppor...

CVE-2021-41209
