Go 漏洞管理工具 govulncheck
前言 在7月份 go 团队正式推出了官方的漏洞检测工具 - govulncheck, govulncheck 默认向 https://vuln.go.dev/ 漏洞数据库请求, 对数据库的请求不包含代码只有使用的包，你也可以使用 -db 来指导所使用的漏洞数据库，所使用的数据库必须实现相应的规范。 govulncheck 具有以下限制: Govulncheck在分析函数指针和接口调用时采用保守的方法，这可能导致一些情况下的误报或不准确的调用堆栈。 使用reflect进行的函数调用对于静态分析是不可见的。仅通过这些调用才能访问的易受攻击的代码将不会被报告。使用unsafe包可能导致漏报。 由于Go二进制文件不包含详细的调用信息，govulncheck无法显示检测到的漏洞的调用图。对于二进制文件中但无法访问的代码，它可能还会报告误报。 目前还不支持 silencing 漏洞发现。请参阅https://go.dev/issue/61211 。 Govulncheck只能读取使用Go 1.18及更高版本编译的二进制文件。 对于无法提取符号信息的二进制文件，govulncheck会报告二进制文件所依赖的所有模块的漏洞。 govulncheck 架构图 govulncheck 还提供了一个可用的 API govulncheck,使开发者能够方便的将 govulncheck 集成到各种工具之中。 安装 通过以下命令安装 govulncheck: go install golang.org/x/vuln/cmd/govulncheck@latest 使用 安装完 govulncheck 后，我们就可以使用了，进入项目路径中，执行 govulncheck ./... 。 以下是我的一个项目的输出: Scanning your code and 508 packages across 71 dependent modules for known vulnerabilities... Vulnerability #1: GO-2023-2102 HTTP/2 rapid reset can cause excessive work in net/http More info: https://pkg.go.dev/vuln/GO-2023-2102 Standard library Found in: net/[email protected] Fixed in: net/[email protected] Example traces found: #1: cmd\xxx\main.go:94:19: xxx.main calls kratos.App.Run, which eventually calls http.Server.Serve #2: cmd\xxx\main.go:94:19: xxx.main calls kratos.App.Run, which eventually calls http.Server.ServeTLS Vulnerability #2: GO-2023-2043 Improper handling of special tags within script contexts in html/template More info: https://pkg.go.dev/vuln/GO-2023-2043 Standard library Found in: html/[email protected] Fixed in: html/[email protected] Example traces found: #1: cmd\xxx\main.go:94:19: xxx.main calls kratos.App.Run, which eventually calls template.Template.Execute #2: cmd\xxx\main.go:94:19: xxx.main calls kratos.App.Run, which eventually calls template.Template.ExecuteTemplate Vulnerability #3: GO-2023-2041 Improper handling of HTML-like comments in script contexts in html/template More info: https://pkg.go.dev/vuln/GO-2023-2041 Standard library Found in: html/[email protected] Fixed in: html/[email protected] Example traces found: #1: cmd\xxx\main.go:94:19: xxx.main calls kratos.App.Run, which eventually calls template.Template.Execute #2: cmd\xxx\main.go:94:19: xxx.main calls kratos.App.Run, which eventually calls template.Template.ExecuteTemplate === Informational === Found 3 vulnerabilities in packages that you import, but there are no call stacks leading to the use of these vulnerabilities. You may not need to take any action. See https://pkg.go.dev/golang.org/x/vuln/cmd/govulncheck for details. Vulnerability #1: GO-2023-2045 Memory exhaustion in QUIC connection handling in crypto/tls More info: https://pkg.go.dev/vuln/GO-2023-2045 Standard library Found in: crypto/[email protected] Fixed in: crypto/[email protected] Vulnerability #2: GO-2023-2044 Panic when processing post-handshake message on QUIC connections in crypto/tls More info: https://pkg.go.dev/vuln/GO-2023-2044 Standard library Found in: crypto/[email protected] Fixed in: crypto/[email protected] Vulnerability #3: GO-2023-1988 Improper rendering of text nodes in golang.org/x/net/html More info: https://pkg.go.dev/vuln/GO-2023-1988 Module: golang.org/x/net Found in: golang.org/x/[email protected] Fixed in: golang.org/x/[email protected] Your code is affected by 3 vulnerabilities from the Go standard library. Share feedback at https://go.dev/s/govulncheck-feedback. 输出内容分为2块，第一块是 Vulnerability 信息，是项目中存在的漏洞，可以看到发现了3个漏洞及具体的原因、触发函数、发现的版本和修复的版本。第二块是 Informational 是一些没有直接引用的包中存在的安全漏洞。 ...
