Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

TeamViewer 全功能 Linux 和 macOS 客户端（15.83 版本之前）中的屏幕图像解码器存在一个越界写入漏洞。远程攻击者可在远程控制会话期间提供特制的屏幕图像数据，从而利用该漏洞执行任意代码。此外，攻击者还可诱使用户打开特制的 TeamViewer 会话录制文件（.tvs）来利用此漏洞。由于解码器缺少对目标边界的检查，特制的屏幕图像数据会导致图像缓冲区发生越界写入。利用该漏洞需要用户交互。

Vulnerability Title
Out-of-bounds Write in TeamViewer Full Client for Linux and macOS Allows Remote Code Execution
Source: CVE Program / CVE List V5
Vulnerability Description
An out-of-bounds write vulnerability in the screen-image decoder of TeamViewer Full Client for Linux and macOS prior to version 15.83 allows a remote attacker to execute arbitrary code by supplying crafted screen-image data during a remote-control session. The vulnerability can also be exploited by persuading a user to open a specially crafted TeamViewer session recording (.tvs). Missing destination bounds checking in the decoder allows crafted screen-image data to cause an out-of-bounds write to the image buffer. Exploitation requires user interaction.
