GHSA-r9px-m959-cxf4
go-git clients vulnerable to DoS via maliciously crafted Git server replies
Quick fix
GHSA-r9px-m959-cxf4 — 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@v5.13.0Details
### Impact 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.
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 `v5.13` 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.
