Denial of service in github.com/go-git/go-git/v5 and gopkg.in/src-d/go-git.v4

Open Source Vulnerabilities CVE-2023-49568

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.

### Impact 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. ### Patches Users running versions of `go-git` from `v4` and above are recommended to upgrade to `v5.11` in order to mitigate this vulnerability. ### Workarounds In cases where a bump to the latest version of `go-git` is not possible, we recommend limiting its use to only trust-worthy Git servers. ## Credit Thanks to Ionut Lalu for responsibly disclosing this vulnerability to us. ### References - [GHSA-mw99-9chc-xw7r](https://github.com/go-git/go-git/security/advisories/GHSA-mw99-9chc-xw7r)
