CVSS: 7.8EPSS: 0%CPEs: 2EXPL: 1CVE-2021-29512 – Heap buffer overflow in `RaggedBinCount`
https://notcve.org/view.php?id=CVE-2021-29512
TensorFlow is an end-to-end open source platform for machine learning. If the `splits` argument of `RaggedBincount` does not specify a valid `SparseTensor`(https://www.tensorflow.org/api_docs/python/tf/sparse/SparseTensor), then an attacker can trigger a heap buffer overflow. This will cause a read from outside the bounds of the `splits` tensor buffer in the implementation of the `RaggedBincount` op(https://github.com/tensorflow/tensorflow/blob/8b677d79167799f71c42fd3fa074476e0295413a/tensorflow/core/kernels/bincount_op.cc#L430-L433). Before the `for` loop, `batch_idx` is set to 0. The user controls the `splits` array, making it contain only one element, 0. • https://github.com/tensorflow/tensorflow/commit/eebb96c2830d48597d055d247c0e9aebaea94cd5 https://github.com/tensorflow/tensorflow/security/advisories/GHSA-4278-2v5v-65r4 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 0%CPEs: 5EXPL: 1CVE-2020-26269 – Heap out of bounds read in filesystem glob matching in TensorFlow
https://notcve.org/view.php?id=CVE-2020-26269
In TensorFlow release candidate versions 2.4.0rc*, the general implementation for matching filesystem paths to globbing pattern is vulnerable to an access out of bounds of the array holding the directories. There are multiple invariants and preconditions that are assumed by the parallel implementation of GetMatchingPaths but are not verified by the PRs introducing it (#40861 and #44310). Thus, we are completely rewriting the implementation to fully specify and validate these. This is patched in version 2.4.0. This issue only impacts master branch and the release candidates for TF version 2.4. • https://github.com/tensorflow/tensorflow/commit/8b5b9dc96666a3a5d27fad7179ff215e3b74b67c https://github.com/tensorflow/tensorflow/security/advisories/GHSA-9jjw-hf72-3mxw • CWE-125: Out-of-bounds Read •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 1CVE-2020-15266 – Undefined behavior in Tensorflow
https://notcve.org/view.php?id=CVE-2020-15266
In Tensorflow before version 2.4.0, when the `boxes` argument of `tf.image.crop_and_resize` has a very large value, the CPU kernel implementation receives it as a C++ `nan` floating point value. Attempting to operate on this is undefined behavior which later produces a segmentation fault. The issue is patched in eccb7ec454e6617738554a255d77f08e60ee0808 and TensorFlow 2.4.0 will be released containing the patch. TensorFlow nightly packages after this commit will also have the issue resolved. En Tensorflow versiones anteriores a 2.4.0, cuando el argumento "boxes" de la función "tf.image.crop_and_resize" presenta un valor muy grande, la implementación del kernel de la CPU lo recibe como un valor de punto flotante "nan" de C++. • https://github.com/tensorflow/tensorflow/issues/42129 https://github.com/tensorflow/tensorflow/pull/42143/commits/3ade2efec2e90c6237de32a19680caaa3ebc2845 https://github.com/tensorflow/tensorflow/security/advisories/GHSA-xwhf-g6j5-j5gc • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 1CVE-2020-15265 – Segfault in Tensorflow
https://notcve.org/view.php?id=CVE-2020-15265
In Tensorflow before version 2.4.0, an attacker can pass an invalid `axis` value to `tf.quantization.quantize_and_dequantize`. This results in accessing a dimension outside the rank of the input tensor in the C++ kernel implementation. However, dim_size only does a DCHECK to validate the argument and then uses it to access the corresponding element of an array. Since in normal builds, `DCHECK`-like macros are no-ops, this results in segfault and access out of bounds of the array. The issue is patched in eccb7ec454e6617738554a255d77f08e60ee0808 and TensorFlow 2.4.0 will be released containing the patch. • https://github.com/tensorflow/tensorflow/commit/eccb7ec454e6617738554a255d77f08e60ee0808 https://github.com/tensorflow/tensorflow/issues/42105 https://github.com/tensorflow/tensorflow/security/advisories/GHSA-rrfp-j2mp-hq9c • CWE-125: Out-of-bounds Read •
