Vulnerability in tensorflow (CVE-2020-15192)
Summary
Vulnerability in tensorflow (CVE-2020-15192). Risk of unauthorized operations or information disclosure. Exploitable via dlpack.to_dlpack. Mitigation: upgrade to 2.3.1 or later.
Original description
The description as published by the source.
In Tensorflow before versions 2.2.1 and 2.3.1, if a user passes a list of strings to dlpack.to_dlpack there is a memory leak following an expected validation failure. The issue occurs because the status argument during validation failures is not properly checked. Since each of the above methods can return an error status, the status value must be checked before continuing. The issue is patched in commit 22e07fb204386768e5bcbea563641ea11f96ceb8 and is released in TensorFlow versions 2.2.1, or 2.3.1.
