High
| Vector | AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N |
Name of the Vulnerable Software and Affected Versions
TensorFlow versions prior to 2.8.0
TensorFlow versions 2.7.1 and earlier
TensorFlow versions 2.6.3 and earlier
TensorFlow versions 2.5.3 and earlier
Description
The implementation of
AddManySparseToTensorsMap is vulnerable to an integer overflow, resulting in a CHECK-fail when building new TensorShape objects. This can cause an assert failure-based denial of service. The issue is due to missing validation on the shapes of the input tensors and directly constructing a large TensorShape with user-provided dimensions.Recommendations
For versions prior to 2.8.0, update to TensorFlow 2.8.0 or later.
For versions 2.7.1 and earlier, update to TensorFlow 2.7.1 or later.
For versions 2.6.3 and earlier, update to TensorFlow 2.6.3 or later.
For versions 2.5.3 and earlier, update to TensorFlow 2.5.3 or later.
As a temporary workaround, consider disabling the
AddManySparseToTensorsMap function until a patch is available.
Restrict access to the TensorShape constructor to minimize the risk of exploitation.
Avoid using user-provided dimensions when constructing TensorShape objects until the issue is resolved.Exploit
