New Bugs Could Let Hackers Bypass Spectre Attack Mitigations On Linux Systems

Cybersecurity researchers on Monday disclosed two new vulnerabilities in Linux-based operating systems that, if successfully exploited, could let attackers circumvent mitigations for speculative attacks such as Spectre and obtain sensitive information from kernel memory. Discovered by Piotr Krysi...

A week in security (November 9 – November 15)

Last week on Malwarebytes Labs, we reported on multiple patch releases: from Mozillas Firefox and Thunderbird to Googles Chrome. We also had a chat with our resident experts, Adam Kujawa and John Donovan, about the future of IoT cybersecurity in our latest Lock and Code podcast episode. Lastly, w...

Memory corruption

In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, if a TFLite saved model uses the same tensor as both input and output of an operator, then, depending on the operator, we can observe a segmentation fault or just memory corruption. We have patched the issue in d58c96946b a...

Segmentation fault in tensorflow-lite

Impact If a TFLite saved model uses the same tensor as both input and output of an operator, then, depending on the operator, we can observe a segmentation fault or just memory corruption. Patches We have patched the issue in d58c96946b and will release patch releases for all versions between 1.1...

GHSA-CVPC-8PHH-8F45 Out of bounds access in tensorflow-lite

Impact In TensorFlow Lite, saved models in the flatbuffer format use a double indexing scheme: a model has a set of subgraphs, each subgraph has a set of operators and each operator has a set of input/output tensors. The flatbuffer format uses indices for the tensors, indexing into an array of...

Segfault and data corruption in tensorflow-lite

Impact To mimic Python's indexing with negative values, TFLite uses ResolveAxis to convert negative values to positive indices. However, the only check that the converted index is now valid is only present in debug builds:...

Denial of Service in Tensorflow

Impact Changing the TensorFlow's SavedModel protocol buffer and altering the name of required keys results in segfaults and data corruption while loading the model. This can cause a denial of service in products using tensorflow-serving or other inference-as-a-service installments. We have added...
