CVE-2018-11235: Path Traversal
First published: Tue May 29 2018(Updated: )
A flaw was found in git which allows arbitrary code to be executed when running 'git clone --recurse-submodules` (or the deprecated 'git clone --recursive' synonym). A malicious repository can include a .gitmodules submodule config file which points outside of the repository. When git clones such a repository it can be tricked into running hooks within the cloned submodule, which is under the control of the attacker.
