Title
Google libwebp开源库远程代码执行漏洞
Description
WebP是Google公司开发的一种图像格式，支持网络图像的有损和无损压缩，其压缩效果和速度较PNG和JPEG格式具有一定优势。libwebp是实现WebP图像格式编解码的C/C++开源库。libwebp通过提供功能函数和系列工具，可将图像数据编码为WebP格式，以及将WebP格式图像进行解码还原。libwebp也可作为依赖库，实现程序对WebP图像格式的支持。libwebp在容器镜像、框架、浏览器、Linux操作系统和应用程序等具有较多应用。 Google libwebp开源库存在远程代码执行漏洞，libwebp的BuildHuffmanTable函数在使用霍夫曼算法（Huffman）对Webp图片进行解码时，由于缺少必要的输入验证，存在内存越界写入缺陷。未经身份认证的攻击者通过制作恶意页面或文件，诱导用户浏览访问执行越界内存写入，实现对目标主机设备的远程任意代码执行或者敏感信息未授权访问。该漏洞在某些环境条件下可被实现零点击利用（0-Click）。
