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. A local user with low privileges can exploit it under high attack complexity to disclose limited information. The sources do not report exploitation.
