暂无补丁情况
官方补丁披露时间
2020-09-15漏洞描述
brotli Library是谷歌（google）的一种数据压缩算法的扩展库使用 LZ77 算法、赫夫曼编码和二阶上下文建模的现代变体组合来压缩数据，其压缩比可与目前可用的最佳通用压缩方法相媲美。 Brotli library 1.0.8之前存在缓冲区错误漏洞，该漏洞源于网络系统或产品在内存上执行操作时，未正确验证数据边界，导致向关联的其他内存位置上执行了错误的读写操作。攻击者可利用该漏洞导致缓冲区溢出或堆溢出等。解决建议
目前厂商已发布升级补丁以修复漏洞，补丁获取链接： https://github.com/google/brotli/releases/tag/v1.0.9
