### Impact Several denial-of-service issues were identified in `go-git` when parsing maliciously crafted Git repository data. An attacker may craft a malicious `.pack`, `.idx` or loose objects that causes an application using an affected version of `go-git` to panic or consume excessive resources. This can lead to denial of service in applications that use `go-git` to clone, fetch, open, or otherwise process untrusted repositories or Git object data. Exploitation requires the ability to alter read-only files such as `.pack` or `.idx` from the local repository's `.git/objects/pack/` directory. Alternatively, the user would need to be interacting with a malicious remote server, which is not recommended and exposes users to a broader class of security risks beyond this issue. ### Patches Users should upgrade to a patched version in order to mitigate this vulnerability. Versions prior to `v5` are likely to be affected, users are recommended to upgrade to a supported `go-git` version. ### Credits go-git thanks @kodareef5, @AyushParkara and @N0zoM1z0 for reporting this in four separate reports. 🙇
