#go#compression#decompression#deflate#go#golang#gzip#snappy#zip#zstandard#zstd The "github.com/klauspost/compress" package offers many fast and efficient compression tools in pure Go, including zstandard, S2 (a faster Snappy replacement), optimized deflate for gzip/zip/zlib, and snappy with better compression and concurrency. It also provides entropy encoders (huff0, FSE), HTTP gzip handlers, and a parallel gzip implementation (pgzip). These tools are drop-in replacements for Go's standard libraries but run about twice as fast, saving time and resources. You can easily add it to your project with `go get`. It supports current and recent Go versions and offers options to disable unsafe code or assembly for compatibility. This package benefits you by improving compression speed and efficiency while maintaining compatibility with standard Go compression APIs, making your applications faster and more resource-friendly. https://github.com/klauspost/compress

CPython zipfile 模块高危漏洞 CVE-2024-8088 CPython 的 zipfile 模块存在一个高危漏洞,编号为 CVE-2024-8088。该漏洞会导致在处理恶意构造的 zip 档案时,程序陷入无限循环。具体来说,当使用 zipfile.Path 类及其方法(如 namelist()`、`iterdir()`、`extractall() 等)遍历 zip 档案条目名称时,可能会触发无限循环。 此漏洞的根本原因在于 zipfile._path._ancestry() 方法中的路径处理不当。具体来说,代码中的 path.rstrip(posixpath.sep) 和 while 循环条件未正确处理路径,导致无限循环。例如,`posixpath.split("//") 返回 ("//", ""),而 "//" != posixpath.sep` 导致循环无法退出。 该漏洞已被修复,建议更新 CPython 并加强输入验证,以防止潜在的拒绝服务攻击。 原文链接:https://www.openwall.com/lists/oss-security/2024/08/22/1https://www.openwall.com/lists/oss-security/2024/08/22/4 标签:#CPython#漏洞#zipfile#无限循环 #AIGC
