Several security issues were fixed in Git.

Summary

Several security issues were fixed in Git.

Software Description:

- git: fast, scalable, distributed revision control system

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

sanity 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)
