Detail

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

- Ubuntu 17.04 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS

Summary:

Git could be made run programs as your login if it opened a specially crafted git repository.

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

Details:

Brian Neel, Joern Schneeweisz, and Jeff King discovered that Git did not properly handle host names in 'ssh://' URLs. A remote attacker could use this to construct a git repository that when accessed could run arbitrary code with the privileges of the user.

Update instructions:

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

Ubuntu 17.04:
git 1:2.11.0-2ubuntu0.2

Ubuntu 16.04 LTS:
git 1:2.7.4-0ubuntu1.2

Ubuntu 14.04 LTS:
git 1:1.9.1-1ubuntu0.6

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