Maliciously crafted Git server replies can cause DoS on go-git clients
Quick fix
GHSA-mw99-9chc-xw7r — github.com/go-git/go-git/v5: upgrade to the fixed version with the command below.
go get github.com/go-git/go-git/v5@v5.11.0Details
### 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.
