Details

Etienne Stalmans discovered that git did not properly validate git
submodules files. A remote attacker could possibly use this to craft a
git repo that causes arbitrary code execution when "git clone
--recurse-submodules" is used. (CVE-2018-11235)

It was discovered that an integer overflow existed in git's pathname
consistency checking code when used on NTFS filesystems. An attacker could
use this to cause a denial of service or expose sensitive information.
(CVE-2018-11233)
