GHSA-CQ76-MXRC-VCHH Crash in `tf.math.segment_*` operations

Impact The implementation of tf.math.segment operations results in a CHECK-fail related abort and denial of service if a segment id in segmentids is large. python import tensorflow as tf tf.math.segmentmaxdata=np.ones1,10,1, segmentids=1676240524292489355 tf.math.segmentmindata=np.ones1,10,1,...

GHSA-J86V-P27C-73FM Unitialized access in `EinsumHelper::ParseEquation`

Impact During execution, EinsumHelper::ParseEquation is supposed to set the flags in inputhasellipsis vector and outputhasellipsis boolean to indicate whether there is ellipsis in the corresponding inputs and output. However, the code only changes these flags to true and never assigns false. cc f...

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...
