Issue Overview:

Git is a revision control system. Prior to versions 2.30.9, 2.31.8, 2.32.7, 2.33.8, 2.34.8, 2.35.8, 2.36.6, 2.37.7, 2.38.5, 2.39.3, and 2.40.1, by feeding specially crafted input to git apply --reject, a path outside the working tree can be overwritten with partially controlled contents (corresponding to the rejected hunk(s) from the given patch). A fix is available in versions 2.30.9, 2.31.8, 2.32.7, 2.33.8, 2.34.8, 2.35.8, 2.36.6, 2.37.7, 2.38.5, 2.39.3, and 2.40.1. As a workaround, avoid using git apply with --reject when applying patches from an untrusted source. Use git apply --stat to inspect a patch before applying; avoid applying one that create a conflict where a link corresponding to the *.rej file exists. (CVE-2023-25652)

Git is a revision control system. Prior to versions 2.30.9, 2.31.8, 2.32.7, 2.33.8, 2.34.8, 2.35.8, 2.36.6, 2.37.7, 2.38.5, 2.39.3, and 2.40.1, a specially crafted .gitmodules file with submodule URLs that are longer than 1024 characters can used to exploit a bug in config.c::git_config_copy_or_rename_section_in_file(). This bug can be used to inject arbitrary configuration into a user’s $GIT_DIR/config when attempting to remove the configuration section associated with that submodule. When the attacker injects configuration values which specify executables to run (such as core.pager, core.editor, core.sshCommand, etc.) this can lead to a remote code execution. A fix A fix is available in versions 2.30.9, 2.31.8, 2.32.7, 2.33.8, 2.34.8, 2.35.8, 2.36.6, 2.37.7, 2.38.5, 2.39.3, and 2.40.1. As a workaround, avoid running git submodule deinit on untrusted repositories or without prior inspection of any submodule sections in $GIT_DIR/config. (CVE-2023-29007)
