## Description

Path traversal vulnerability in Apache MINA SSHD bundle sshd-git. Lack of
path validation in git-upload-pack, git-receive-pack, and other git
operations allows users authenticated over SSH access to git repositories
outside the configured git server root directory.
Applications are affected if they use org.apache.sshd:sshd-git.
Applications not using sshd-git are not affected.
Users are advised to upgrade affected applications to Apche MINA SSHD
2.18.0, which fixes the issue.
The issue also is present in the pre-release milestones 3.0.0-M1 to
3.0.0-M3 for a new upcoming new major version 3.0.0. Again, applications
are affected only if they use sshd-git. Upgrade affected applications to
3.0.0-M4.
We would like to point out that a professional git server should not rely
solely on file system layout and permissions, but should implement
additional security controls to govern access to git repositories and
operations allowed on particular git repositories.
