USN-3671-1: Git vulnerabilities

5 June 2018

Several security issues were fixed in Git.



  • git - fast, scalable, distributed revision control system


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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 18.04
Ubuntu 17.10
Ubuntu 16.04
Ubuntu 14.04

In general, a standard system update will make all the necessary changes.
