CVE-2021-37646

CVE-2021-37646 affects TensorFlow: the StringNGrams implementation can overflow when converting a negative, signed ngram_width to an unsigned size during a reserve call, enabling a potential denial-of-service condition. The root cause is a signed-to-unsigned conversion in TF’s string buffer alloc...

CVE-2021-37661 Crash caused by integer conversion to unsigned in TensorFlow

TensorFlow is an end-to-end open source platform for machine learning. In affected versions an attacker can cause a denial of service in boostedtreescreatequantilestreamresource by using negative arguments. The implementation does not validate that numstreams only contains non-negative numbers. I...

CVE-2021-37661

Summary: CVE-2021-37661 affects TensorFlow and causes a denial of service via the boosted_trees_create_quantile_stream_resource path when a negative number of streams is supplied. The code does not validate that num_streams is non-negative before using it to reserve memory, leading to an implicit...
