CVE-2025-21614: go-git clients vulnerable to DoS via maliciously crafted Git server replies

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.
