Description
A flaw was found in the way the git-remote-ext helper processed certain URLs. If a user had Git configured to automatically clone submodules from untrusted repositories, an attacker could inject commands into the URL of a submodule, allowing them to execute arbitrary code on the user's system.
CVSS score applicability
The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.
Mitigation
Avoid recursive cloning or updating of git submodules without checking the submodule URL. Non-recursive cloning is the default in git, so user needs to change this to become vulnerable ("e.g. by specifying --recursive").
