CVE-2021-4122

It was found that a specially crafted LUKS header could trick cryptsetup into disabling encryption during the recovery of the device. An attacker with physical access to the medium, such as a flash disk, could use this flaw to force a user into permanently disabling the encryption layer of that...

GHSA-XRQM-FPGR-6HHX Overflow/crash in `tf.range`

Impact 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 will be cast to double and the result would be truncated before the...

GHSA-PGCQ-H79J-2F69 Incomplete validation of shapes in multiple TF ops

Impact 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 but in some scenarios writes and reads from heap populated arrays are als...

GHSA-7V94-64HJ-M82H FPE in `ParallelConcat`

Impact The implementation of ParallelConcat misses some input validation and can produce a division by 0: python import tensorflow as tf @tf.function def test: y = tf.rawops.ParallelConcatvalues='tf',shape=0 return y test Patches We have patched the issue in GitHub commit...
