Git client vulnerability
Yesterday a critical Git security vulnerability was announced that affects all versions of the official Git client and all related software that interacts with Git repositories.
While GitHub Enterprise itself is not directly affected, it may be used as a distribution point for an attacker to reach unpatched clients. This release detects and blocks malicious trees from being pushed to an Enterprise instance, eliminating it as an attack vector.
It it critical to note that this release only provides mitigation against low-levels attacks where a user with write access could attempt to push malicious files to a GitHub Enterprise instance. It does not prevent interactions with malicious external Git servers that can open up command-line level attack vectors, as those must be dealt with at the Git client level.
For full protection, we strongly recommend you ensure that all developers update their Git clients, in addition to upgrading to this release. Installing this update alone does not mean your organization is fully safe against this vulnerability. The only way to make sure none of your developers are vulnerable is to have everyone upgrade their Git client.
More details on the vulnerability can be found in the official Git mailing list announcement, on the git-blame blog, and on the GitHub blog.
