Vulnerability Details

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.
