Detailed vulnerability description

The vulnerability allows a local user to read and write outside the bounds of heap-allocated data and cause a denial of service.

The vulnerability exists due to out-of-bounds read and out-of-bounds write in boosted trees code in tensorflow/core/kernels/boosted_trees/stats_ops.cc when processing crafted input to boosted trees APIs. A local user can supply crafted input to trigger out-of-bounds memory access and denial of service.

The denial of service can occur through null pointer dereferences or CHECK failures.
