high Nessus 插件 ID 321144
语言：
简介
Linux/Unix 主机上安装的一个或多个程序包存在漏洞，但供应商表示不会修补此漏洞。描述
Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。- 在 GStreamer 的 librfb（RFB/VNC 客户端）中发现一个堆缓冲区溢出漏洞。矩形边界检查未正确验证区域而非单个尺寸，从而允许恶意 VNC 服务器发送延伸到帧缓冲区之外的矩形。远程攻击者可设置恶意的 VNC 服务器并诱骗用户进行连接，从而造成越界堆写入，进而导致代码执行或崩溃。(CVE-2026-52720)
请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
