Summary
jgit security update
Details

A pure Java implementation of the Git version control system and command line interface.

Security Fix(es):

Arbitrary File Overwrite in Eclipse JGit <= 6.6.0

In Eclipse JGit, all versions <= 6.6.0.202305301015-r, a symbolic link present in a specially crafted git repository can be used to write a file to locations outside the working tree when this repository is cloned with JGit to a case-insensitive filesystem, or when a checkout from a clone of such a repository is performed on a case-insensitive filesystem.

This can happen on checkout (DirCacheCheckout), merge (ResolveMerger via its WorkingTreeUpdater), pull (PullCommand using merge), and when applying a patch (PatchApplier). This can be exploited for remote code execution (RCE), for instance if the file written outside the working tree is a git filter that gets executed on a subsequent git command.

The issue occurs only on case-insensitive filesystems, like the default filesystems on Windows and macOS. The user performing the clone or checkout must have the rights to create symbolic links for the problem to occur, and symbolic links must be enabled in the git configuration.

Setting git configuration option core.symlinks = false before checking out avoids the problem.

The issue was fixed in Eclipse JGit version 6.6.1.202309021850-r and 6.7.0.202309050840-r, available via Maven Central https://repo1.maven.org/maven2/org/eclipse/jgit/  and repo.eclipse.org https://repo.eclipse.org/content/repositories/jgit-releases/ .

The JGit maintainers would like to thank RyotaK for finding and reporting this issue.
