Descriptions

A path traversal vulnerability was discovered in go-git versions prior to v5.11. This vulnerability allows an attacker to create and amend files across the filesystem. In the worse case scenario, remote code execution could be achieved.

Applications are only affected if they are using the ChrootOS https://pkg.go.dev/github.com/go-git/go-billy/v5/osfs#ChrootOS , which is the default when using "Plain" versions of Open and Clone funcs (e.g. PlainClone). Applications using BoundOS https://pkg.go.dev/github.com/go-git/go-billy/v5/osfs#BoundOS  or in-memory filesystems are not affected by this issue.
This is a go-git implementation issue and does not affect the upstream git cli.

Se descubrió una vulnerabilidad de path traversal en versiones de go-git anteriores a la v5.11. Esta vulnerabilidad permite a un atacante crear y modificar archivos en todo el sistema de archivos. En el peor de los casos, se podría lograr la ejecución remota de código. Las aplicaciones solo se ven afectadas si usan ChrootOS https://pkg.go.dev/github.com/go-git/go-billy/v5/osfs#ChrootOS, que es el valor predeterminado cuando se usan versiones "simples" de Open y funciones de clonación (por ejemplo, PlainClone). Las aplicaciones que utilizan BoundOS https://pkg.go.dev/github.com/go-git/go-billy/v5/osfs#BoundOS o sistemas de archivos en memoria no se ven afectados por este problema. Este es un problema de implementación de go-git y no afecta el cli de git ascendente.

A path traversal vulnerability was discovered in the go library go-git. This issue may allow an attacker to create and amend files across the filesystem when applications are using the default ChrootOS, potentially allowing remote code execution.
