This +function is also used by `git receive-pack` (i.e. pushes), by `git +upload-archive`, by `git daemon` and by `git http-backend`. In setups +that want to serve repositories owned by different users than the +account running the service, this will require `safe.*` settings to be +configured accordingly. + +Also note: there are tiny time windows where a time-of-check-time-of-use +("TOCTOU") race is possible. The real solution to those would be to work +with `fstat()` and `openat()`. However, the latter function is not +available on Windows (and would have to be emulated with rather +expensive low-level `NtCreateFile()` calls), and the changes would be +quite extensive, for my taste too extensive for the little gain given +that embargoed releases need to pay extra attention to avoid introducing +inadvertent bugs. + +Signed-off-by: Johannes Schindelin +--- + cache.h | 12 ++++++++++++ + path.c | 2 ++ + setup.c | 21 +++++++++++++++++++++ + t/t0411-clone-from-partial.sh | 6 +++--- + 4 files changed, 38 insertions(+), 3 deletions(-) + +diff --git a/cache.h b/cache.h +index fcf49706a..a46a3e4b6 100644 +--- a/cache.h ++++ b/cache.h +@@ -606,6 +606,18 @@ void set_git_work_tree(const char *tree);

To +optimize this even further, we try to hardlink files into place instead +of copying data over, which helps both disk usage and speed. + +There is an important edge case in this context though, namely when we +try to hardlink symlinks from the source repository into the target +repository. Depending on both platform and filesystem the resulting +behaviour here can be different: + + - On macOS and NetBSD, calling link(3P) with a symlink target creates + a hardlink to the file pointed to by the symlink. + + - On Linux, calling link(3P) instead creates a hardlink to the symlink + itself. + +To unify this behaviour, 36596fd2df (clone: better handle symlinked +files at .git/objects/, 2019-07-10) introduced logic to resolve symlinks +before we try to link(3P) files. Consequently, the new behaviour was to +always create a hard link to the target of the symlink on all platforms. + +Eventually though, we figured out that following symlinks like this can +cause havoc when performing a local clone of a malicious repository, +which resulted in CVE-2022-39253. This issue was fixed via 6f054f9fb3 +(builtin/clone.c: disallow `--local` clones with symlinks, 2022-07-28), +by refusing symlinks in the source repository. + +But even though we now shouldn't ever link symlinks anymore, the code +that resolves symlinks still exists. In the best case the code does not +end up doing anything because there are no symlinks anymore. In the +worst case though this can be abused by an adversary that rewrites the +source file after it has been checked not to be a symlink such that it +actually is a symlink when we call link(3P). Thus, it is still possible +to recreate CVE-2022-39253 due to this time-of-check-time-of-use bug. + +Remove the call to `realpath()`.

But if the server side of a fetch or a +clone is a partial clone, then either upload-pack or its child +pack-objects may run a lazy "git fetch" under the hood. And it is very +easy to convince fetch to run arbitrary commands. + +The "server" side can be a local repository owned by someone else, who +would be able to configure commands that are run during a clone with the +current user's permissions. This issue has been designated +CVE-2024-32004. + +The fix in this commit's parent helps in this scenario, as well as in +related scenarios using SSH to clone, where the untrusted .git directory +is owned by a different user id. But if you received one as a zip file, +on a USB stick, etc, it may be owned by your user but still untrusted. + +This has been designated CVE-2024-32465. + +To mitigate the issue more completely, let's disable lazy fetching +entirely during `upload-pack`. While fetching from a partial repository +should be relatively rare, it is certainly not an unreasonable workflow. +And thus we need to provide an escape hatch. + +This commit works by respecting a GIT_NO_LAZY_FETCH environment variable +(to skip the lazy-fetch), and setting it in upload-pack, but only when +the user has not already done so (which gives us the escape hatch). + +The name of the variable is specifically chosen to match what has +already been added in 'master' via e6d5479e7a (git: extend +--no-lazy-fetch to work across subprocesses, 2024-02-27). Since we're +building this fix as a backport for older versions, we could cherry-pick +that patch and its earlier steps. However, we don't really need the +niceties (like a "--no-lazy-fetch" option) that it offers. By using the +same name, everything should just work when the two are eventually +merged, but here are a few notes: + + - the blocking of the fetch in e6d5479e7a is incomplete! It sets + fetch_if_missing to 0 when we setup the repository variable, but + that isn't enough. pack-objects in particular will call + prefetch_to_pack() even if that variable is 0. This patch by + contrast checks the environment variable at the lowest level before + we call the lazy fetch, where we can be sure to catch all code + paths. + + Possibly the setting of fetch_if_missing from e6d5479e7a can be + reverted, but it may be useful to have. For example, some code may + want to use that flag to change behavior before it gets to the point + of trying to start the fetch. At any rate, that's all outside the + scope of this patch. + + - there's documentation for GIT_NO_LAZY_FETCH in e6d5479e7a. We can + live without that here, because for the most part the user shouldn't + need to set it themselves. The exception is if they do want to + override upload-pack's default, and that requires a separate + documentation section (which is added here) + + - it would be nice to use the NO_LAZY_FETCH_ENVIRONMENT macro added by + e6d5479e7a, but those definitions have moved from cache.h to + environment.h between 2.39.3 and master. I just used the raw string + literals, and we can replace them with the macro once this topic is + merged to master. + +At least with respect to CVE-2024-32004, this does render this commit's +parent commit somewhat redundant. However, it is worth retaining that +commit as defense in depth, and because it may help other issues (e.g., +symlink/hardlink TOCTOU races, where zip files are not really an +interesting attack vector). + +The tests in t0411 still pass, but now we have _two_ mechanisms ensuring +that the evil command is not run. Let's beef up the existing ones to +check that they failed for the expected reason, that we refused to run +upload-pack at all with an alternate user id.
