Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Eclipse JGit versions from 6.0.0.202111291000-r up to 6.6.1.202309021850-r (exclusive) and from 5.13.3.202401111512-r (exclusive) are affected. A specially crafted repository with a symbolic link can make JGit write files outside the working tree when it is cloned or checked out on a case-insensitive filesystem, such as default Windows or macOS setups; the user must be able to create symbolic links. This can lead to remote code execution. Upgrade to 6.6.1.202309021850-r or 5.13.3.202401111512-r. As a workaround, set core.symlinks to false before checking out.
