In git.index.base.IndexFile.from_tree, control was never able tofall off the end, but mypy reported a "Missing return statement"because it could not infer that the context manager didn't suppressany exceptions.This was for two reasons. An ExitStack context manager suppressesexceptions in some uses and not others, depending on the contextmanager objects its enter_context method is called with. In thiscase, that was sufficient to produce the mypy warning regardless ofother changes, so I converted it to nested with-statements. Thenesting depth is only 2, so this is not really any worse. (I alsoreworded the comments for clarity and adjusted their spacing.)The more important cause, however, could also produce this warningin code that uses GitPython, as git.index.util.TemporaryFileSwap ispublic. Its __exit__ method was annotated to return bool. This wasitself reported by mypy as an error, because a context manager__exit__ method that never suppresses exceptions should eitheralways (implicitly) return None and be annotated as such, or it canreturn False as this implementation does but should then have itsreturn type annotated as Literal[False].So this also changes TemporaryFileSwap.__exit__'s return typeannotation from bool to Literal[False]. If this were nonpublic orbeing newly designed, it may be better for it to instead returnNone implicitly, but I think that would technically be a breakingchange (though it would be very unusual, and not a good idea, forany code to ever rely on the distinction).With both these changes made, both those mypy warnings go away, andcode using GitPython will not get a warning if it makes similardirect use of TemporaryFileSwap.(An alternative might be to dedent the return statement out of thewith-statement in IndexFile.from_tree, but this would make lessclear to readers that it does not suppress exceptions. Furthermore,the change to TemporaryFileSwap.__exit__ would still have to bemade for mypy to consider it correctly typed.)
Thanks again for all your great work! GitPython seems to have a limitless supply of little and big issues to fix 😅. I just noticed that the commit message is the PR message, but with markdown annotations removed. Personally, I'd love to think that soon we will have tools that will render commit messages as markdown to make having such annotations valuable, and even if not I find markdown easy-enough on the eye to look at it verbatim. Please do feel free to write markdown in commit messages (and even subject lines) to have less work in cases like these. |
This is descriptively accurate, but the sequence was that I wrote it without Markdown, and then added the Markdown later. I'm accustomed to writing commit messages with little to no Markdown, and sometimes it would actually be easier for me to do so even if adding Markdown later. (This is not the case for text in general; I don't wait to add Markdown later in most documents that will ultimately be Markdown.)
Thanks. There are definitely also some situations where writing it once with Markdown will be easier, and I'll strive to remember that option. This kind of a side issue, but one narrow situation where I've found it is very useful to put Markdown in a commit message (when the commit is going on GitHub) is when talking about a specific decorator and writing its name with Likewise, one situation where I've found it more important than usual to put Markdown in a pull request description is when otherwise a name with leading or trailing double-underscores would appear without them and in bold. I can see that a benefit of writing pull request titles in Markdown (usually I don't) is when something like this appears in them. The titles appear unrendered in most places, but in automatically generated release notes they are rendered, so one gets things like "del" when one means " |

OnWindows, GitPython uses an untrusted search path if it uses a shell torun `git`, as well as when it runs `bash.exe` to interpret hooks. Ifeither of those features are used on Windows, a malicious `git.exe` or`bash.exe` may be run from an untrusted repository.### DetailsAlthough GitPython often avoids executing programs found in an untrustedsearch path since 3.1.33, two situations remain where this still occurs.Either can allow arbitrary code execution under some circumstances.#### When a shell is usedGitPython can be told to run `git` commands through a shell rather thanas direct subprocesses, by passing `shell=True` to any method thataccepts it, or by both setting `Git.USE_SHELL = True` and not passing`shell=False`. Then the Windows `cmd.exe` shell process performs thepath search, and GitPython does not prevent that shell from finding andrunning `git` in the current directory.When GitPython runs `git` directly rather than through a shell, theGitPython process performs the path search, and currently omits thecurrent directory by setting `NoDefaultCurrentDirectoryInExePath` in itsown environment during the `Popen` call. Although the `cmd.exe` shellwill honor this environment variable when present, GitPython does notcurrently pass it into the shell subprocess's environment.Furthermore, because GitPython sets the subprocess CWD to the root of arepository's working tree, using a shell will run a malicious `git.exe`in an untrusted repository even if GitPython itself is run from atrusted location.This also applies if `Git.execute` is called directly with `shell=True`(or after `Git.USE_SHELL = True`) to run any command.#### When hook scripts are runOn Windows, GitPython uses `bash.exe` to run hooks that appear to bescripts. However, unlike when running `git`, no steps are taken to avoidfinding and running `bash.exe` in the current directory.This allows the author of an untrusted fork or branch to cause amalicious `bash.exe` to be run in some otherwise safe workflows. Anexample of such a scenario is if the user installs a trusted hook whileon a trusted branch, then switches to an untrusted feature branch(possibly from a fork) to review proposed changes. If the untrustedfeature branch contains a malicious `bash.exe` and the user's currentworking directory is the working tree, and the user performs an actionthat runs the hook, then although the hook itself is uncorrupted, itruns with the malicious `bash.exe`.Note that, while `bash.exe` is a shell, this is a separate scenario fromwhen `git` is run using the unrelated Windows `cmd.exe` shell.### PoCOn Windows, create a `git.exe` file in a repository. Then create a`Repo` object, and call any method through it (directly or indirectly)that supports the `shell` keyword argument with `shell=True`:```powershellmkdir testrepogit init testrepocp ... testrepo git.exe # Replace "..." with any executable of choice.python -c "import git; print(git.Repo('testrepo').git.version(shell=True))"```The `git.exe` executable in the repository directory will be run.Or use no `Repo` object, but do it from the location with the `git.exe`:```powershellcd testrepopython -c "import git; print(git.Git().version(shell=True))"```The `git.exe` executable in the current directory will be run.For the scenario with hooks, install a hook in a repository, create a`bash.exe` file in the current directory, and perform an operation thatcauses GitPython to attempt to run the hook:```powershellmkdir testrepocd testrepogit initmv .git/hooks/pre-commit.sample .git/hooks/pre-commitcp ... bash.exe # Replace "..." with any executable of choice.echo "Some text" >file.txtgit add file.txtpython -c "import git; git.Repo().index.commit('Some message')"```The `bash.exe` executable in the current directory will be run.### ImpactThe greatest impact is probably in applications that set `Git.USE_SHELL= True` for historical reasons. (Undesired console windows had, in thepast, been created in some kinds of applications, when it was not used.)Such an application may be vulnerable to arbitrary code execution from amalicious repository, even with no other exacerbating conditions. Thisis to say that, if a shell is used to run `git`, the full effect ofCVE-2023-40590 is still present. Furthermore, as noted above, runningthe application itself from a trusted directory is not a sufficientmitigation.An application that does not direct GitPython to use a shell to run`git` subprocesses thus avoids most of the risk. However, there is nosuch straightforward way to prevent GitPython from running `bash.exe` tointerpret hooks. So while the conditions needed for that to be exploitedare more involved, it may be harder to mitigate decisively prior topatching.### Possible solutionsA straightforward approach would be to address each bug directly:- When a shell is used, pass `NoDefaultCurrentDirectoryInExePath` intothe subprocess environment, because in that scenario the subprocess isthe `cmd.exe` shell that itself performs the path search.- Set `NoDefaultCurrentDirectoryInExePath` in the GitPython processenvironment during the `Popen` call made to run hooks with a `bash.exe`subprocess.These need only be done on Windows.---### Release Notes<details><summary>gitpython-developers/GitPython (GitPython)</summary>###[`v3.1.41`](https://togithub.com/gitpython-developers/GitPython/releases/tag/3.1.41):- fix Windows

In
git.index.base.IndexFile.from_tree, control was never able to fall off the end, butmypyreported a "Missing return statement" because it could not infer that the context manager didn't suppress any exceptions.This was for two reasons. An
ExitStackcontext manager suppresses exceptions in some uses and not others, depending on the context manager objects itsenter_contextmethod is called with. In this case, that was sufficient to produce themypywarning regardless of other changes, so I converted it to nestedwith-statements. The nesting depth is only 2, so this is not really any worse. (I also reworded the comments for clarity and adjusted their spacing.)The more important cause, however, could also produce this warning in code that uses GitPython, as
git.index.util.TemporaryFileSwapis public. Its__exit__method was annotated to returnbool. This was itself reported bymypyas an error, because a context manager__exit__method that never suppresses exceptions should either always (implicitly) returnNoneand be annotated as such, or it can returnFalseas this implementation does but should then have its return type annotated asLiteral[False].So this also changes
TemporaryFileSwap.__exit__'s return type annotation frombooltoLiteral[False]. If this were nonpublic or being newly designed, it may be better for it to instead returnNoneimplicitly, but I think that would technically be a breaking change (though it would be very unusual, and not a good idea, for any code to ever rely on the distinction).With both these changes made, both those
mypywarnings go away, and code using GitPython will not get a warning if it makes similar direct use ofTemporaryFileSwap.(An alternative might be to dedent the return statement out of the
with-statement inIndexFile.from_tree, but this would make less clear to readers that it does not suppress exceptions. Furthermore, the change toTemporaryFileSwap.__exit__would still have to be made formypyto consider it correctly typed.)
