Summary
Tanium Threat Response Client Extension is affected, as are Tanium Endpoint Configuration Toolset Solution versions from 1.71.0 before 1.71.25, from 1.59.0 before 1.59.50 and from 1.51.0 before 1.51.60. The flaw is an out-of-bounds read (CWE-125) that lets the software read memory outside its intended bounds.
