Use after free in `DecodePng` kernel

  • Disclosed: 04.02.2022
  • Updated: 11.10.2026 14:17

Impact

A malicious user can cause a use after free behavior when decoding PNG images:

cc
if (/* ... error conditions ... */) {
  png::CommonFreeDecode(&decode);
  OP_REQUIRES(context, false,
              errors::InvalidArgument("PNG size too large for int: ",
                                      decode.width, " by ", decode.height));
}

After png::CommonFreeDecode(&decode) gets called, the values of decode.width and decode.height are in an unspecified state.

Patches

We have patched the issue in GitHub commit e746adbfcfee15e9cfdb391ff746c765b99bdf9b.

The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.
