A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.04 LTS
- Ubuntu 17.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
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)
