CVE-2020-15207

Advisory

Intel-tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1 include a fix for CVE-2020-15207: In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, to mimic Python's indexing with negative values, TFLite uses 'ResolveAxis' to convert negative values to positive indices. However, the only check that the converted index is now valid is only present in debug builds. If the 'DCHECK' does not trigger, then code execution moves ahead with a negative index. This, in turn, results in accessing data out of bounds which results in segfaults and/or data corruption.
