Code execution via truncated configuration-line parsing
Published Apr 25, 2023 · Updated Nov 4, 2025
Configuration injection in Git allows attackers to execute arbitrary code after a user processes a crafted repository and deinitializes a submodule. git_config_copy_or_rename_section_in_file() reads configuration through a fixed 1,024-byte buffer, causing text after a split to be parsed as a new section rather than as the remainder of a value. Exploitation requires local user interaction with an untrusted repository; injected executable settings can then run with that user's privileges.
