    valgrind vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 17.04
    - Ubuntu 16.10
    - Ubuntu 16.04 LTS
    - Ubuntu 14.04 LTS
    
    Summary:
    
    Valgrind could be made to crash or run programs if it opened a specially
    crafted file.
    
    Software Description:
    - valgrind: instrumentation framework for building dynamic analysis tools
    
    Details:
    
    It was discovered that Valgrind incorrectly handled certain string
    operations. If a user or automated system were tricked into processing a
    specially crafted binary, a remote attacker could possibly execute
    arbitrary code. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04
    LTS and Ubuntu 16.10. (CVE-2016-2226)
    
    It was discovered that Valgrind 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
    Valgrind to crash, resulting in a denial of service. (CVE-2016-4487,
    CVE-2016-4488, CVE-2016-4489, CVE-2016-4490, CVE-2016-4491, CVE-2016-4492,
    CVE-2016-4493, CVE-2016-6131)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 17.04:
      valgrind                        1:3.12.0-1ubuntu1.1
    
    Ubuntu 16.10:
      valgrind                        1:3.12.0~svn20160714-1ubuntu2.1
    
    Ubuntu 16.04 LTS:
      valgrind                        1:3.11.0-1ubuntu4.2
    
    Ubuntu 14.04 LTS:
      valgrind                        1:3.10.1-1ubuntu3~14.5
    
    In general, a standard system update will make all the necessary changes.
