CVE-2022-24765

Git for Windows is a fork of Git containing Windows-specific patches. This
vulnerability affects users working on multi-user machines, where untrusted
parties have write access to the same hard disk. Those untrusted parties
could create the folder C:\.git, which would be picked up by Git
operations run supposedly outside a repository while searching for a Git
directory. Git would then respect any config in said Git directory. Git
Bash users who set GIT_PS1_SHOWDIRTYSTATE are vulnerable as well. Users
who installed posh-gitare vulnerable simply by starting a PowerShell. Users
of IDEs such as Visual Studio are vulnerable: simply creating a new project
would already read and respect the config specified in C:\.git\config.
Users of the Microsoft fork of Git are vulnerable simply by starting a Git
Bash. The problem has been patched in Git for Windows v2.35.2. Users unable
to upgrade may create the folder .git on all drives where Git commands
are run, and remove read/write access from those folders as a workaround.
Alternatively, define or extend GIT_CEILING_DIRECTORIES to cover the
parent directory of the user profile, e.g. C:\Users if the user profile
is located in C:\Users\my-user-name.
