    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.
