PYSEC-2021-625

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...

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...

Stack overflow

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...

PYSEC-2021-637

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...

CVE-2021-41222

TensorFlow SplitV vulnerability (CVE-2021-41222) causes a segmentation fault when size_splits contains more than one value and at least one value is negative. Affected TensorFlow versions include those in the 2.x series referenced for backporting fixes; the issue is resolved by the TensorFlow 2.7...

CVE-2021-41228

CVE-2021-41228 affects TensorFlow’s saved_model_cli, where user-supplied strings are passed to eval, enabling code injection. The vulnerability exists in affected TensorFlow releases’ saved_model_cli tool and can allow arbitrary code execution on the host where the CLI runs. Public documentation ...

CVE-2021-41220 Use after free in `CollectiveReduceV2`

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...

CVE-2021-41220

CVE-2021-41220 (TensorFlow) — Normal details The vulnerability affects TensorFlow's async CollectiveReduceV2, causing a memory leak and use-after-free when objects moved via std::move are still accessed during asynchronous processing. The issue path is described in the CVE entry and related advis...

CVE-2021-41221 Access to invalid memory during shape inference in `Cudnn*` ops

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-2021-41221

TensorFlow’s CVE-2021-41221 relates to a heap-based memory access in the shape inference code for Cudnn* ops. Root cause: ranks of input, input_h, and input_c are not validated, allowing invalid memory access. Fix planned for TensorFlow 2.7.0 with cherry-picks to 2.6.1, 2.5.2, and 2.4.4. Remediat...

CVE-2021-41202

TensorFlow is an open source platform for machine learning. In affected versions while calculating the size of the output within the tf.range kernel, there is a conditional statement of type int64 = condition ? int64 : double. Due to C++ implicit conversion rules, both branches of the condition...

CVE-2021-41206

TensorFlow is an open source platform for machine learning. In affected versions several TensorFlow operations are missing validation for the shapes of the tensor arguments involved in the call. Depending on the API, this can result in undefined behavior and segfault or CHECK-fail related crashes...

CVE-2021-41208

TensorFlow is an open source platform for machine learning. In affected versions the code for boosted trees in TensorFlow is still missing validation. As a result, attackers can trigger denial of service via dereferencing nullptrs or via CHECK-failures as well as abuse undefined behavior binding...

CVE-2021-41218

TensorFlow is an open source platform for machine learning. In affected versions the shape inference code for AllToAll can be made to execute a division by 0. This occurs whenever the splitcount argument is 0. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on...
