CVE-2020-8927 (CNNVD-202009-910)
中文标题:
Google brotli Library 缓冲区错误漏洞
英文标题:
Buffer overflow in Brotli library
漏洞描述
中文描述:
Google brotli Library是美国谷歌(Google)公司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。 Google brotli Library 1.0.8之前版本存在缓冲区错误漏洞,攻击者控制脚本的一次性解压缩请求的输入长度可能会触发崩溃。
英文描述:
A buffer overflow exists in the Brotli library versions prior to 1.0.8 where an attacker controlling the input length of a "one-shot" decompression request to a script can trigger a crash, which happens when copying over chunks of data larger than 2 GiB. It is recommended to update your Brotli library to 1.0.8 or later. If one cannot update, we recommend to use the "streaming" API as opposed to the "one-shot" API, and impose chunk size limits.
