go-git improperly verifies data integrity values for .idx and .pack files

go-git is a highly extensible git implementation library written in pure Go. Prior to 5.16.5, a vulnerability was discovered in go-git whereby data integrity values for .pack and .idx files were not properly verified. This resulted in go-git potentially consuming corrupted files, which would likely result in unexpected errors such as object not found. For context, clients fetch packfiles from upstream Git servers. Those files contain a checksum of their contents, so that clients can perform integrity checks before consuming it. The pack indexes (.idx) are generated locally by go-git, or the git cli, when new .pack files are received and processed. The integrity checks for both files were not being verified correctly. This vulnerability is fixed in 5.16.5.

完整性检查值验证不恰当

go-git 安全漏洞

go-git是go-git开源的一个用纯 Go 编写的高度可扩展的 git 实现库。 go-git 5.16.5之前版本存在安全漏洞，该漏洞源于.pack和.idx文件的数据完整性值未正确验证，可能导致使用损坏文件并引发错误。
