New Report Links Research Firms BIETA and CIII to China's MSS Cyber Operations

A Chinese company named the Beijing Institute of Electronics Technology and Application BIETA has been assessed to be likely led by the Ministry of State Security MSS. The assessment comes from evidence that at least four BIETA personnel have clear or possible links to MSS officers and their...

TensorFlow vulnerable to `CHECK` fail in `FakeQuantWithMinMaxVars`

TensorFlow vulnerable to `CHECK` fail in `CollectiveGather`

Impact When CollectiveGather receives an scalar input input, it gives a CHECK fails that can be used to trigger a denial of service attack. python import tensorflow as tf arg0=1 arg1=1 arg2=1 arg3=1 arg4=3, 3,3 arg5='auto' arg6=0 arg7='' tf.rawops.CollectiveGatherinput=arg0, groupsize=arg1,...

TensorFlow vulnerable to null dereference on MLIR on empty function attributes

Impact Eig can be fed an incorrect Tout input, resulting in a CHECK fail that can trigger a denial of service attack. python import tensorflow as tf import numpy as np arg0=tf.constantvalue=np.random.randomsize=2, 2, shape=2, 2, dtype=tf.float32 arg1=tf.complex128 arg2=True arg3=''...

TensorFlow vulnerable to `CHECK` fail in `DrawBoundingBoxes`

Impact When DrawBoundingBoxes receives an input boxes that is not of dtype float, it gives a CHECK fail that can trigger a denial of service attack. python import tensorflow as tf import numpy as np arg0=tf.constantvalue=np.random.randomsize=1, 3, 2, 3, shape=1, 3, 2, 3, dtype=tf.half...

TensorFlow vulnerable to `CHECK` fail in `Unbatch`

Impact When Unbatch receives a nonscalar input id, it gives a CHECK fail that can trigger a denial of service attack. python import tensorflow as tf import numpy as np arg0=tf.constantvalue=np.random.randomsize=3, 3, 1, dtype=tf.float64 arg1=tf.constantvalue=np.random.randint0,100,size=3, 3, 1,...

Impact When RandomPoissonV2 receives large input shape and rates, it gives a CHECK fail that can trigger a denial of service attack. python import tensorflow as tf arg0=tf.random.uniformshape=4,, dtype=tf.int32, maxval=65536 arg1=tf.random.uniformshape=4, 4, 4, 4, 4, dtype=tf.float32, maxval=None...

TensorFlow vulnerable to `CHECK` fail in `AudioSummaryV2`

Impact When AudioSummaryV2 receives an input samplerate with more than one element, it gives a CHECK fails that can be used to trigger a denial of service attack. python import tensorflow as tf arg0='' arg1=tf.random.uniformshape=1,1, dtype=tf.float32, maxval=None arg2=tf.random.uniformshape=2,1,...

TensorFlow vulnerable to `CHECK` fail in `tf.random.gamma`
