CVE-2020-15206 Information

Description

In Tensorflow before versions 1.15.4 2.0.3 2.1.2 2.2.1 and 2.3.1 changing the TensorFlow’s SavedModel protocol buffer and altering the name of required keys results in segfaults and data corruption while loading the model. This can cause a denial of service in products using tensorflow-serving or other inference-as-a-service installments. Fixed were added in commits f760f88b4267d981e13f4b302c437ae800445968 and fcfef195637c6e365577829c4d67681695956e7d (both going into TensorFlow 2.2.0 and 2.3.0 but not yet backported to earlier versions). However this was not enough as 41097 reports a different failure mode. The issue is patched in commit adf095206f25471e864a8e63a0f1caef53a0e3a6 and is released in TensorFlow versions 1.15.4 2.0.3 2.1.2 2.2.1 or 2.3.1.
