git: arbitrary code execution when recursively cloning a malicious repository

Published May 30, 2018

Description

In Git before 2.13.7, 2.14.x before 2.14.4, 2.15.x before 2.15.2, 2.16.x before 2.16.4, and 2.17.x before 2.17.1, remote code execution can occur. With a crafted .gitmodules file, a malicious project can execute an arbitrary script on a machine that runs "git clone --recurse-submodules" because submodule "names" are obtained from this file, and then appended to $GIT_DIR/modules, leading to directory traversal with "../" in a name. Finally, post-checkout hooks from a submodule are executed, bypassing the intended design in which hooks are not obtained from a remote server.

Affected products

Remediation

Red Hat statement

This issue did not affect the versions of git as shipped with Red Hat Enterprise Linux 6 as they did not include the vulnerable code. If using OCP 3.6 make sure atomic-openshift-3.6.173.0.128-1.git.0.8da0828.el7 or later is installed on the master.

Red Hat mitigation

Don't create OCP source-to-image applications from source code repositories hosted by untrusted parties. Github is blocking users from pushing repositories with malicious submodules so it's less likely you can pull a malicious repository from there which triggers this vulnerability.
