Detailed vulnerability description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to improper validation of submodule "names" supplied via the untrusted .gitmodules file when appending them to the '$GIT_DIR/modules' directory. A remote attacker can return specially crafted data to create or overwrite files on the target user's system when the repository is cloned and execute arbitrary code with elevated privileges.
