medium Nessus 插件 ID 348227
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 Poppler 的 Splash 后端中发现一个拒绝服务缺陷。如果特制的平铺图案几何接近 int32 边界，则可造成 SplashOutputDev：：tilingPatternFill 计算受攻击者控制的重复计数，从而在没有相应内存分配的情况下，驱动图案填充扫描线例程中的过长循环。攻击者可将恶意 PDF 提供给通过 Poppler 启动后端渲染该文件的应用程序来利用此漏洞，从而导致渲染进程在由攻击者控制的较长时间内消耗 100% CPU。（CVE-2026-93653）
请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
