The information on this page was manually curated by our Cybersecurity Intelligence Team.
Tensorflow version 2.6.1 includes a fix for CVE-2021-41211: In affected versions, the shape inference code for 'QuantizeV2' can trigger a read outside of bounds of heap allocated array. This occurs whenever 'axis' is a negative value less than '-1'. In this case, we are accessing data before the start of a heap buffer. The code allows 'axis' to be an optional argument ('s' would contain an 'error::NOT_FOUND' error code). Otherwise, it assumes that 'axis' is a valid index into the dimensions of the 'input' tensor. If 'axis' is less than '-1' then this results in a heap OOB read. The fix is included in TensorFlow 2.7.0.

TensorFlow is an open source machine learning framework for everyone.
TensorFlow is an open source platform for machine learning. In affected versions the shape inference code for `QuantizeV2` can trigger a read outside of bounds of heap allocated array. This occurs whenever `axis` is a negative value less than `-1`. In this case, we are accessing data before the start of a heap buffer. The code allows `axis` to be an optional argument (`s` would contain an `error::NOT_FOUND` error code). Otherwise, it assumes that `axis` is a valid index into the dimensions of the `input` tensor. If `axis` is less than `-1` then this results in a heap OOB read. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, as this version is the only one that is also affected. See CVE-2021-41211.
