    perl vulnerabilities
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 15.10
    - Ubuntu 14.04 LTS
    - Ubuntu 12.04 LTS
    Several security issues were fixed in Perl.
    Software Description:
    - perl: Practical Extraction and Report Language
    It was discovered that Perl incorrectly handled certain regular expressions
    with an invalid backreference. An attacker could use this issue to cause
    Perl to crash, resulting in a denial of service, or possibly execute
    arbitrary code. (CVE-2013-7422)
    Markus Vervier discovered that Perl incorrectly handled nesting in the
    Data::Dumper module. An attacker could use this issue to cause Perl to
    consume memory and crash, resulting in a denial of service. (CVE-2014-4330)
    Stephane Chazelas discovered that Perl incorrectly handled duplicate
    environment variables. An attacker could possibly use this issue to bypass
    the taint protection mechanism. (CVE-2016-2381)
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 15.10:
      perl                            5.20.2-6ubuntu0.2
    Ubuntu 14.04 LTS:
      perl                            5.18.2-2ubuntu1.1
    Ubuntu 12.04 LTS:
      perl                            5.14.2-6ubuntu2.5
    In general, a standard system update will make all the necessary changes.
