Security Update for Multiple Vulnerabilities in TeamViewer Clients and Related Services
Multiple high-severity vulnerabilities affecting TeamViewer Full Client and Host on Windows, Linux, and macOS have been addressed in version 15.82. These include local privilege escalations via path traversal and race conditions, a heap-based buffer overflow leading to potential remote code execution, and an access control bypass allowing unauthorized remote actions. The vulnerabilities impact versions prior to 15.82 and some legacy versions. TeamViewer strongly recommends updating to version 15.82 or later to mitigate these issues. No active exploitation or public disclosure is currently known.
AI Analysis
Technical Summary
TeamViewer released security updates fixing multiple vulnerabilities in their Full Client and Host products across Windows, Linux, and macOS platforms. Key issues include: (1) a path traversal vulnerability (CVE-2026-19743) allowing local privilege escalation via crafted IPC commands; (2) a heap-based buffer overflow in session recording playback (CVE-2026-92368) potentially enabling remote code execution when opening malicious session files; (3) a TOCTOU race condition in the Windows installer rollback mechanism (CVE-2026-92369) leading to local privilege escalation; (4) an improper access control vulnerability (CVE-2026-92370) permitting authenticated remote attackers to bypass user-configured permissions and possibly execute code remotely; and (5) a local privilege escalation via improper link resolution in Cloud Session Recording on Linux (CVE-2026-92371). All these vulnerabilities are resolved in TeamViewer version 15.82 and supported legacy releases. No known active exploitation or public disclosure exists.
Potential Impact
Successful exploitation of these vulnerabilities could allow local attackers to escalate privileges to SYSTEM/root, and remote authenticated attackers to bypass access controls potentially leading to remote code execution. The vulnerabilities affect confidentiality, integrity, and availability of affected systems. However, there is no evidence of active exploitation in the wild at this time.
Mitigation Recommendations
TeamViewer has released fixed versions (15.82 and later) addressing all identified vulnerabilities. Users and administrators should promptly update all affected TeamViewer Full Client and Host installations to version 15.82 or later. No additional mitigations are specified or required beyond applying the official updates.
