Ubuntu Security Notice USN-3243-1
March 23, 2017

git vulnerability
==========================================================================

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

- Ubuntu 14.04 LTS

Summary:

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

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

Details:

It was discovered that Git incorrectly sanitized branch names in the PS1
variable when configured to display the repository status in the shell
prompt. If a user were tricked into exploring a malicious repository, a
remote attacker could use this issue to execute arbitrary code.

Update instructions:

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

Ubuntu 14.04 LTS:
git 1:1.9.1-1ubuntu0.4

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