Ubuntu Security Notice USN-3671-1
June 05, 2018
git vulnerabilities
==========================================================================
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)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 18.04 LTS:
git 1:2.17.1-1ubuntu0.1
Ubuntu 17.10:
git 1:2.14.1-1ubuntu4.1
Ubuntu 16.04 LTS:
git 1:2.7.4-0ubuntu1.4
Ubuntu 14.04 LTS:
git 1:1.9.1-1ubuntu0.8
In general, a standard system update will make all the necessary changes.
