high Nessus 插件 ID 276641
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。- LIBPNG 是一个参考库在读取、创建和操纵 PNG可移植网络图形栅格图像文件的应用程序中使用。从版本 1.6.0 到 1.6.51之前的版本png_image_read_composite 中处理启用了 PNG_FLAG_OPTIMIZE_ALPHA 的调色板图像时存在越界读取漏洞。png_init_read_transformations 中的调色板复合代码在预乘期间未正确应用背景复合从而违反了简化的 PNG API 所需的不变组件 alpha 257。已在版本 1.6.51 中修补此问题。(CVE-2025-64720)
请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
