CVE-2023-49568: Go-git project go-git improper input validation vulnerability

GGo Git Project · Go Git

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.
