The remote host is running a version of Mac OS X 10.7, 10.8, or 10.9 that does not have Security Update 2014-002 applied. This update contains several security-related fixes for the following components :

  - CFNetwork HTTPProtocl
  - CoreServicesUIAgent
  - FontParser
  - Heimdal Kerberos
  - ImageIO
  - Intel Graphics Driver
  - IOKit Kernel
  - Kernel
  - Power Management
  - Ruby
  - Security - Secure Transport
  - Window Server

Note that successful exploitation of the most serious issues could result in arbitrary code execution.

The remote Mac OS X 10.9 host has a version of OS X Server installed that is prior to 3.1.2. It is, therefore, affected by a heap-based buffer overflow vulnerability in the Ruby component that occurs when converting a string to a floating point value. A remote attacker can exploit this, via a specially crafted request to Profile Manager or to a Ruby script, to cause a denial of service condition or the execution of arbitrary code.

Updated ruby packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having critical security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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

A buffer overflow flaw was found in the way Ruby parsed floating point numbers from their text representation. If an application using Ruby accepted untrusted input strings and converted them to floating point numbers, an attacker able to provide such input could cause the application to crash or, possibly, execute arbitrary code with the privileges of the application. (CVE-2013-4164)

All ruby users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.

The remote Solaris system is missing necessary patches to address security updates :

  - 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)

An overflow in floating point number parsing was found in Ruby currently being shipped on Fedora 19. This vulnerability has been assigned the CVE identifier CVE-2013-4164.

This new rpm should fix this issue.

The remote Mac OS X host has a version of OS X Server installed that is prior to version 4.0.  It is, therefore, affected by the following vulnerabilities :

  - There are multiple vulnerabilities within the included     BIND, the most serious of which can lead to a denial of     service. (CVE-2013-3919, CVE-2013-4854, CVE-2014-0591)

  - There are multiple vulnerabilities within the included     LibYAML for the Profile Manager and ServerRuby, the most     serious of which can lead to arbitrary code execution.
    (CVE-2013-4164, CVE-2013-6393)

  - There are multiple vulnerabilities within the included     PostgreSQL, the most serious of which can lead to     arbitrary code execution. (CVE-2014-0060, CVE-2014-0061,     CVE-2014-0062, CVE-2014-0063, CVE-2014-0064,     CVE-2014-0065, CVE-2014-0066)

  - An error exists related to the way SSL 3.0 handles     padding bytes when decrypting messages encrypted using     block ciphers in cipher block chaining (CBC) mode. A     man-in-the-middle attacker can decrypt a selected byte     of a cipher text in as few as 256 tries if they are able     to force a victim application to repeatedly send the     same data over newly created SSL 3.0 connections. This     is also known as the 'POODLE' issue. (CVE-2014-3566)

  - A cross-site scripting flaw exists in the Xcode Server     due to not properly validating input before returning it     to the user. This can allow a remote attacker, using a     specially crafted request, to execute code within the     browser / server trust relationship. (CVE-2014-4406)

  - A SQL injection flaw exists in the Wiki Server due to     not properly sanitizing user input before using it in     SQL queries. This can allow a remote attacker, using a     specially crafted request, to inject or manipulate SQL     queries, thus allowing the manipulation or disclosure     of arbitrary data. (CVE-2014-4424)

  - A restriction bypass flaw exists in the Mail Server due     to SCAL changes being cached and not enforced until the     service had restarted. This can allow an authenticated     remote attacker to bypass those restrictions.
    (CVE-2014-4446)

  - A password disclosure flaw exists in the Profile Manager     due to passwords being potentially saved to a file when     editing or setting up a profile. This can allow a local     attacker to gain access to password information.
    (CVE-2014-4447)

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)

The following security issue has been fixed :

  - heap overflow in float point parsing. (CVE-2013-4164)

New ruby packages are available for Slackware 13.1, 13.37, 14.0, 14.1, and -current to fix a security issue.

According to its self-reported version number, the Puppet Enterprise 3.x install on the remote host is prior to 3.1.1.  As a result, it is reportedly affected by multiple vulnerabilities :

  - An input validation error exists related to the     included Ruby version, handling string to floating point     conversions that could allow denial of service attacks     or arbitrary code execution. (CVE-2013-4164)

  - An error exists related to the included RubyGems     version and 'gem build', 'Gem::Package', and     'Gem::PackageTask' API calls that could allow denial     of service attacks. (CVE-2013-4363)

  - An error exists in the 'i18n' gem for Ruby that could     allow cross-site scripting attacks. (CVE-2013-4491)

  - An error exists related to handling temporary files     that could allow a local attacker to overwrite files by     using a symlink attack. (CVE-2013-4969)

  - An error exists related to the included Ruby on Rails,     'Action View', and handling certain headers that could     allow denial of service attacks. (CVE-2013-6414)

  - An input validation error exists related to the     included Ruby on Rails and the 'unit' parameter in the     'number_to_currency' helper that could allow cross-site     scripting attacks. (CVE-2013-6415)

  - An input validation error exists related to the     included Ruby on Rails, JSON parameter parsing and SQL     queries that could allow SQL injection attacks.
    (CVE-2013-6417)

Several vulnerabilities have been discovered in the interpreter for the Ruby language. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2013-1821     Ben Murphy discovered that unrestricted entity expansion     in REXML can lead to a Denial of Service by consuming     all host memory.

  - CVE-2013-4073     William (B.J.) Snow Orvis discovered a vulnerability in     the hostname checking in Ruby's SSL client that could     allow man-in-the-middle attackers to spoof SSL servers     via a crafted certificate issued by a trusted     certification authority.

  - CVE-2013-4164     Charlie Somerville discovered that Ruby incorrectly     handled floating point number conversion. If an     application using Ruby accepted untrusted input strings     and converted them to floating point numbers, an     attacker able to provide such input could cause the     application to crash or, possibly, execute arbitrary     code with the privileges of the application.

Charlie Somerville discovered that Ruby incorrectly handled floating point number conversion. An attacker could possibly use this issue with an application that converts text to floating point numbers to cause the application to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2013-4164)

Vit Ondruch discovered that Ruby did not perform taint checking for certain functions. An attacker could possibly use this issue to bypass certain intended restrictions. (CVE-2013-2065).
