REDHAT-BUG-2168160
First published: Wed Feb 08 2023(Updated: )
Using a specially-crafted repository, Git can be tricked into using its local clone optimization even when using a non-local transport. Though Git will abort local clones whose source $GIT_DIR/objects directory contains symbolic links (c.f., <a href="https://access.redhat.com/security/cve/CVE-2022-39253">CVE-2022-39253</a>), 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 <a href="https://access.redhat.com/security/cve/CVE-2022-39253">CVE-2022-39253</a>.
