A critical Git security vulnerability has been announced today, affecting all versions of the \
official Git client and all related software that interacts with Git repositories, including \
GitHub for Windows and GitHub for Mac. Because this is a client-side only vulnerability, \
github.com and GitHub Enterprise are not directly affected.

The vulnerability concerns Git and Git-compatible clients that access Git repositories in a \
case-insensitive or case-normalizing filesystem. An attacker can craft a malicious Git tree that \
will cause Git to overwrite its own .git/config file when cloning or checking out a repository, \
leading to arbitrary command execution in the client machine. Git clients running on OS X (HFS+) \
or any version of Microsoft Windows (NTFS, FAT) are exploitable through this vulnerability. Linux \
clients are not affected if they run in a case-sensitive filesystem.

We strongly encourage all users of GitHub and GitHub Enterprise to update their Git clients as \
soon as possible, and to be particularly careful when cloning or accessing Git repositories hosted \
on unsafe or untrusted hosts.

Repositories hosted on github.com cannot contain any of the malicious trees that trigger the \
vulnerability because we now verify and block these trees on push. We have also completed an \
automated scan of all existing content on github.com to look for malicious content that might have \
been pushed to our site before this vulnerability was discovered. This work is an extension of the \
data-quality checks we have always performed on repositories pushed to our servers to protect our \
users against malformed or malicious Git data.

Updated versions of GitHub for Windows and GitHub for Mac are available for immediate download, and \
both contain the security fix on the Desktop application itself and on the bundled version of the \
Git command-line client.

In addition, the following updated versions of Git address this vulnerability:


The Git core team has announced maintenance releases for all current versions of Git (v1.8.5.6, \
v1.9.5, v2.0.5, v2.1.4, and v2.2.1).
Git for Windows (also known as MSysGit) has released maintenance version 1.9.5.
The two major Git libraries, libgit2 and JGit, have released maintenance versions with the fix. \
Third party software using these libraries is strongly encouraged to update.


More details on the vulnerability can be found in the official Git mailing list announcement and on \
the git-blame blog.
