![]() The problem is that when you git clone a repository, there is some important configuration that you don’t get from the server. Therefore git can skip the fetch and simply check out the submodule using the repository that’s on disk. It will then realize that it doesn’t need to do the clone – the submodule’s repository already exists on disk since it was checked in to the parent, it was written to the working directory when it was checked out. When recursively cloning this repository, git will first checkout the parent repository into the working directory, then prepare to clone the submodule. What is the Git vulnerability?Ī remote repository may contain a definition for a submodule, and also bundle that submodule’s repository data, checked in to the parent repository as a folder. If you are using other Git clients, please contact your vendor to understand if you need to upgrade and how to do that. Visual Studio 2017 users should install updates both Visual Studio 15.7.3 and 15.0.14 include updates to fix this vulnerability. ![]() If you’re using Git for Windows, please download the latest version - 2.17.1(2) - from. This will ensure that we cannot be used as a vector for transmitting maliciously crafted repositories to users who have not yet patched their clients for this vulnerability. To further protect you, our team has blocked these types of malicious repositories from being pushed to VSTS. The Visual Studio Team Services (VSTS) team takes security issues very seriously, and we encourage all users to update their Git clients as soon as possible to fix this vulnerability. Git for Windows 2.17.1 (2) has been released that includes this fix. Git 2.17.1 was released today and includes this fix. This vulnerability has been assigned CVE 2018-11235 by Mitre, the organization that assigns unique numbers to track security vulnerabilities in software. The code shack gave a hattip to 俞晨东 for finding the bug and Johannes Schindelin for working on a fix.The Git community has disclosed an industry-wide security vulnerability in Git that can lead to arbitrary code execution when a user operates in a malicious repository. git folder themselves and remove read/write access as workaround or "define or extend 'GIT_CEILING_DIRECTORIES' to cover the parent directory of the user profile," according to NIST. To deal with the issue, the Git team recommends an update. ![]() These need to be multi-user machines, likely running Windows (probably due to how the file system of the OS works.) Ultimately, it is an arbitrary code issue, if one that requires access to the disk to implement. Not nice, but also very specific in terms of affected systems. The Git team was little blunter about the vulnerability, and warned that "Merely having a Git-aware prompt that runs 'git status' (or 'git diff') and navigating to a directory which is supposedly not a Git worktree, or opening such a directory in an editor or IDE such as VS Code or Atom, will potentially run commands defined by that other user." Complaints mount after GitHub launches new algorithmic feed. ![]() ![]() Git security vulnerability could lead to an attack of the (repo) clones.Open-source Kubernetes tool Argo CD has a high-severity path traversal flaw: Patch now.Windows is now built on Git, but Microsoft has found some bottlenecks."Users of the Microsoft fork of Git are vulnerable simply by starting a Git Bash." NIST went on to list potentially vulnerable products, which included Visual Studio. ![]()
