    libiberty vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    
    Summary:
    
    Several security issues were fixed in libiberty.
    
    Software Description:
    - libiberty: library of utility functions used by GNU programs
    
    Details:
    
    It was discovered that libiberty incorrectly handled parsing certain
    binaries. If a user or automated system were tricked into processing a
    specially crafted binary, a remote attacker could use this issue to cause
    libiberty to crash, resulting in a denial of service, or possibly execute
    arbitrary code
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 18.04 LTS:
      libiberty-dev                   20170913-1ubuntu0.1
    
    Ubuntu 16.04 LTS:
      libiberty-dev                   20160215-1ubuntu0.3
    
    In general, a standard system update will make all the necessary changes.
