CVE-2019-1387

Public on 2019-12-09
Modified on 2020-03-23
Description

A flaw was discovered where git improperly validates submodules' names used to construct git metadata paths and does not prevent them from being nested in existing directories used to store another submodule's metadata. A remote attacker could abuse this flaw to trick a victim user into cloning a malicious repository containing submodules, which, when recursively cloned, would trigger the flaw and remotely execute code on the victim's machine.
