Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.04 LTS - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS

Summary:

Git could be made to run programs as your login if it recursively opened a malicious git repository.

Software Description: - git: fast, scalable, distributed revision control system

Details:

It was discovered that git did not properly validate git submodule urls or paths. A remote attacker could possibly use this to craft a git repository that causes arbitrary code execution when recursive operations are used.

Update instructions:

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

Ubuntu 18.04 LTS:
git 1:2.17.1-1ubuntu0.3

Ubuntu 16.04 LTS:
git 1:2.7.4-0ubuntu1.5

Ubuntu 14.04 LTS:
git 1:1.9.1-1ubuntu0.9

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