"The ruby interpreter received a fix for two security issues :

  - Ruby's $SAFE mechanism enables untrusted user codes to
    run in $SAFE >= 4 mode. This is a kind of sandboxing so
    some operations are restricted in that mode to protect
    other data outside the sandbox. (CVE-2012-4466)

    The problem found was around this mechanism.
    Exception#to_s, NameError#to_s, and name_err_mesg_to_s()
    interpreter-internal API was not correctly handling the
    $SAFE bits so a String object which is not tainted can
    destructively be marked as tainted using them. By using
    this an untrusted code in a sandbox can modify a
    formerly-untainted string destructively.

    http://www.ruby-lang.org/en/news/2012/10/12/cve-2012-446
    4-cve-2012-4466/

  - Ruby before 1.8.7-p352 does not reset the random seed
    upon forking, which makes it easier for
    context-dependent attackers to predict the values of
    random numbers by leveraging knowledge of the number
    sequence obtained in a different child process.
    (CVE-2011-2686)

  - Fix entity expansion DoS vulnerability in REXML. When
    reading text nodes from an XML document, the REXML
    parser could be coerced into allocating extremely large
    string objects which could consume all available memory
    on the system. (CVE-2013-1821)"

"According to the versions of the ruby packages installed, the EulerOS
Virtualization installation on the remote host is affected by the
following vulnerabilities :

  - Ruby 1.8.7 before patchlevel 371, 1.9.3 before
    patchlevel 286, and 2.0 before revision r37068 allows
    context-dependent attackers to bypass safe-level
    restrictions and modify untainted strings via the
    name_err_mesg_to_str API function, which marks the
    string as tainted, a different vulnerability than
    CVE-2011-1005.(CVE-2012-4466)

  - The REXML parser in Ruby 1.9.x before 1.9.3 patchlevel
    551, 2.0.x before 2.0.0 patchlevel 598, and 2.1.x
    before 2.1.5 allows remote attackers to cause a denial
    of service (CPU and memory consumption) a crafted XML
    document containing an empty string in an entity that
    is used in a large number of nested entity references,
    aka an XML Entity Expansion (XEE) attack. NOTE: this
    vulnerability exists because of an incomplete fix for
    CVE-2013-1821 and CVE-2014-8080.(CVE-2014-8090)

  - Algorithmic complexity vulnerability in
    Gem::Version::VERSION_PATTERN in
    lib/rubygems/version.rb in RubyGems before 1.8.23.1,
    1.8.24 through 1.8.25, 2.0.x before 2.0.8, and 2.1.x
    before 2.1.0, as used in Ruby 1.9.0 through 2.0.0p247,
    allows remote attackers to cause a denial of service
    (CPU consumption) via a crafted gem version that
    triggers a large amount of backtracking in a regular
    expression.(CVE-2013-4287)

  - The REXML parser in Ruby 1.9.x before 1.9.3-p550, 2.0.x
    before 2.0.0-p594, and 2.1.x before 2.1.4 allows remote
    attackers to cause a denial of service (memory
    consumption) via a crafted XML document, aka an XML
    Entity Expansion (XEE) attack.(CVE-2014-8080)

  - The OpenSSL::SSL.verify_certificate_identity function
    in lib/openssl/ssl.rb in Ruby 1.8 before 1.8.7-p374,
    1.9 before 1.9.3-p448, and 2.0 before 2.0.0-p247 does
    not properly handle a '\\0' character in a domain name
    in the Subject Alternative Name field of an X.509
    certificate, which allows man-in-the-middle attackers
    to spoof arbitrary SSL servers via a crafted
    certificate issued by a legitimate Certification
    Authority, a related issue to
    CVE-2009-2408.(CVE-2013-4073)

  - The rb_get_path_check function in file.c in Ruby 1.9.3
    before patchlevel 286 and Ruby 2.0.0 before r37163
    allows context-dependent attackers to create files in
    unexpected locations or with unexpected names via a NUL
    byte in a file path.(CVE-2012-4522)

  - (1) DL and (2) Fiddle in Ruby 1.9 before 1.9.3
    patchlevel 426, and 2.0 before 2.0.0 patchlevel 195, do
    not perform taint checking for native functions, which
    allows context-dependent attackers to bypass intended
    $SAFE level restrictions.(CVE-2013-2065)

  - Algorithmic complexity vulnerability in
    Gem::Version::ANCHORED_VERSION_PATTERN in
    lib/rubygems/version.rb in RubyGems before 1.8.23.2,
    1.8.24 through 1.8.26, 2.0.x before 2.0.10, and 2.1.x
    before 2.1.5, as used in Ruby 1.9.0 through 2.0.0p247,
    allows remote attackers to cause a denial of service
    (CPU consumption) via a crafted gem version that
    triggers a large amount of backtracking in a regular
    expression. NOTE: this issue is due to an incomplete
    fix for CVE-2013-4287.(CVE-2013-4363)

  - Ruby (aka CRuby) 1.9 before 1.9.3-p327 and 2.0 before
    r37575 computes hash values without properly
    restricting the ability to trigger hash collisions
    predictably, which allows context-dependent attackers
    to cause a denial of service (CPU consumption) via
    crafted input to an application that maintains a hash
    table, as demonstrated by a universal multicollision
    attack against a variant of the MurmurHash2 algorithm,
    a different vulnerability than
    CVE-2011-4815.(CVE-2012-5371)

  - Off-by-one error in the encodes function in pack.c in
    Ruby 1.9.3 and earlier, and 2.x through 2.1.2, when
    using certain format string specifiers, allows
    context-dependent attackers to cause a denial of
    service (segmentation fault) via vectors that trigger a
    stack-based buffer overflow.(CVE-2014-4975)

  - Heap-based buffer overflow in Ruby 1.8, 1.9 before
    1.9.3-p484, 2.0 before 2.0.0-p353, 2.1 before 2.1.0
    preview2, and trunk before revision 43780 allows
    context-dependent attackers to cause a denial of
    service (segmentation fault) and possibly execute
    arbitrary code via a string that is converted to a
    floating point value, as demonstrated using (1) the
    to_f method or (2) JSON.parse.(CVE-2013-4164)

  - It was found that the methods from the Dir class did
    not properly handle strings containing the NULL byte.
    An attacker, able to inject NULL bytes in a path, could
    possibly trigger an unspecified behavior of the ruby
    script.(CVE-2018-8780)

  - Ruby 1.9.3 before patchlevel 286 and 2.0 before
    revision r37068 allows context-dependent attackers to
    bypass safe-level restrictions and modify untainted
    strings via the (1) exc_to_s or (2) name_err_to_s API
    function, which marks the string as tainted, a
    different vulnerability than CVE-2012-4466. NOTE: this
    issue might exist because of a CVE-2011-1005
    regression.(CVE-2012-4464)

  - An issue was discovered in the OpenSSL library in Ruby
    before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2,
    and 2.6.x before 2.6.0-preview3. When two
    OpenSSL::X509::Name objects are compared using ==,
    depending on the ordering, non-equal objects may return
    true. When the first argument is one character longer
    than the second, or the second argument contains a
    character that is one less than a character in the same
    position of the first argument, the result of == will
    be true. This could be leveraged to create an
    illegitimate certificate that may be accepted as
    legitimate and then used in signing or encryption
    operations.(CVE-2018-16395)

  - An issue was discovered in Ruby before 2.3.8, 2.4.x
    before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before
    2.6.0-preview3. It does not taint strings that result
    from unpacking tainted strings with some
    formats.(CVE-2018-16396)

description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");

The Red Hat Security Response Team has rated this update as having
moderate security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

Ruby is an extensible, interpreted, object-oriented, scripting
language. It has features to process text files and to do system
management tasks.

It was found that certain methods did not sanitize file names before
passing them to lower layer routines in Ruby. If a Ruby application
created files with names based on untrusted input, it could result in
the creation of files with different names than expected.
(CVE-2012-4522)

It was found that the RHSA-2011:0909 update did not correctly fix the
CVE-2011-1005 issue, a flaw in the method for translating an exception
message into a string in the Exception class. A remote attacker could
use this flaw to bypass safe level 4 restrictions, allowing untrusted
(tainted) code to modify arbitrary, trusted (untainted) strings, which
safe level 4 restrictions would otherwise prevent. (CVE-2012-4481)

The CVE-2012-4481 issue was discovered by Vit Ondruch of Red Hat.

This update also fixes the following bug :

* Prior to this update, the 'rb_syck_mktime' option could, under
certain circumstances, terminate with a segmentation fault when
installing libraries with certain gems. This update modifies the
underlying code so that Ruby gems can be installed as expected.
(BZ#834381)

which contain backported patches to resolve these issues."

A vulnerability was found that file creation routines can create
unintended files by strategically inserting NUL(s) in file paths. This
vulnerability has been reported as CVE-2012-4522.

Ruby can handle arbitrary binary patterns as Strings, including NUL
chars. On the other hand OSes and other libraries tend not. They
usually treat a NUL as an End of String mark. So to interface them
with Ruby, NUL chars should properly be avoided.

However methods like IO#open did not check the filename passed to
them, and just passed those strings to lower layer routines. This led
to create unintentional files."
