clone optimization even when using a non-local transport. Though Git will
abort local clones whose source $GIT_DIR/objects directory contains symbolic
links, the objects directory itself may still be a symbolic link. These two
may be combined to include arbitrary files based on known paths on the
victim's filesystem within the malicious repository's working copy, allowing
for data exfiltration in a similar manner as CVE-2022-39253 (CVE-2023-22490).

By feeding a crafted input to 'git apply', a path outside the working tree can
be overwritten as the user who is running 'git apply' (CVE-2023-23946).");
