CVE-2022-21733

Advisory

Tensorflow-rocm versions 2.5.3, 2.6.3, 2.7.1 and 2.8.0 include a fix for CVE-2022-21733: The implementation of 'StringNGrams' can be used to trigger a denial of service attack by causing an out of memory condition after an integer overflow. There is missing a validation on 'pad_witdh' and that result in computing a negative value for 'ngram_width' which is later used to allocate parts of the output.
