Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

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.

Fix

Vendor fix Red Hat Product Security RHSA-2018:2147 · 134 productsFor details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258
Workaround from the vendor Red Hat Product Security RHSA-2018:2147 · 134 productsDon'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.
