TeamViewer < 13.2.36231 / 14.x < 14.7.48868 / 15.x < 15.64.10 / 15.65.x < 15.83 Heap Overflow (TV-2026-1011)

high Nessus Plugin ID 377055

Synopsis

A remote access client on the remote Windows host is affected by a heap-based buffer overflow vulnerability.

Description

The version of TeamViewer installed on the remote Windows host is prior to 13.2.36231, 14.x prior to 14.7.48868, 15.x prior to 15.64.10, or 15.65.x prior to 15.83. It is, therefore, affected by a vulnerability as referenced in the TV-2026-1011 advisory:

- An integer overflow in the remote-control screen processing component of TeamViewer clients (Full Client, Portable and Remote Control App) prior to version 15.83 may allow a malicious remote host to cause a denial of service or, depending on the platform, potentially execute arbitrary code with the privileges of the viewer process. Exploitation requires a user to establish a remote-control session to an attacker-controlled or compromised host. (CVE-2026-111585)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade TeamViewer to version 13.2.36231, 14.7.48868, 15.64.10 (Windows 7 and 8), 15.83, or later.
