A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.
Description
Improper access control in the Patch Management update mechanism of TeamViewer Full Client and Host for Windows prior to version 15.82 allows a local authenticated attacker with low privileges to supply a signed executable through a forged IPC response and cause it to load a malicious DLL from a user-writable temporary directory. Successful exploitation results in arbitrary code execution with NT AUTHORITY\SYSTEM privileges.
