QID 352285: Amazon Linux Security Update for git: AL2012-2020-299

Package updates are available for Amazon Linux that fix the following vulnerabilities:
CVE-2019-1387: 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. Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.
