Ubuntu Security Notice USN-3671-1

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.
