CVE-2023-49568

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.

Summary		(es) Se descubrió una vulnerabilidad de denegación de servicio (DoS) en versiones de go-git anteriores a la v5.11. Esta vulnerabilidad permite a un atacante realizar ataques de denegación de servicio proporcionando respuestas especialmente manipuladas desde un servidor Git que provoca el agotamiento de los recursos en los clientes go-git. Las aplicaciones que utilizan únicamente el sistema de archivos en memoria compatible con go-git no se ven afectadas por esta vulnerabilidad. Este es un problema de implementación de go-git y no afecta el cli de git ascendente.
