CVE-2023-49568: Maliciously crafted Git server replies can cause DoS on go-git clients
First published: Wed Dec 27 2023(Updated: )
### 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)
