There are 4 open security issues in bookworm.
2 important issues:
- CVE-2025-21613:
go-git is a highly extensible git implementation library written in pure Go. An argument injection vulnerability was discovered in go-git versions prior to v5.13. Successful exploitation of this vulnerability could allow an attacker to set arbitrary values to git-upload-pack flags. This only happens when the file transport protocol is being used, as that is the only protocol that shells out to git binaries. This vulnerability is fixed in 5.13.0.
- CVE-2025-21614:
go-git is a highly extensible git implementation library written in pure Go. A denial of service (DoS) vulnerability was discovered in go-git versions prior to v5.13. This vulnerability allows an attacker to perform denial of service attacks by providing specially crafted responses from a Git server which triggers resource exhaustion in go-git clients. Users running versions of go-git from v4 and above are recommended to upgrade to v5.13 in order to mitigate this vulnerability.
2 issues left for the package maintainer to handle:
- CVE-2023-49568:
(needs triaging)
A denial of service (DoS) vulnerability was discovered in go-git versions prior to v5.11. This vulnerability allows an attacker to perform denial of service attacks by providing specially crafted responses from a Git server which triggers resource exhaustion in go-git clients. Applications using only the in-memory filesystem supported by go-git are not affected by this vulnerability. This is a go-git implementation issue and does not affect the upstream git cli.
- CVE-2023-49569:
(needs triaging)
A path traversal vulnerability was discovered in go-git versions prior to v5.11. This vulnerability allows an attacker to create and amend files across the filesystem. In the worse case scenario, remote code execution could be achieved. Applications are only affected if they are using the ChrootOS https://pkg.go.dev/github.com/go-git/go-billy/v5/osfs#ChrootOS , which is the default when using "Plain" versions of Open and Clone funcs (e.g. PlainClone). Applications using BoundOS https://pkg.go.dev/github.com/go-git/go-billy/v5/osfs#BoundOS or in-memory filesystems are not affected by this issue. This is a go-git implementation issue and does not affect the upstream git cli.
You can find information about how to handle these issues in the security team's documentation.
