Hi,

The following vulnerabilities were published for go-git.

CVE-2023-49568[0]:
| 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.


CVE-2023-49569[1]:
| 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.


If you fix the vulnerabilities please also make sure to include the
