  - 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)

Updated Grid component packages that fix multiple security issues are now available for Red Hat Enterprise MRG 2.4 for Red Hat Enterprise Linux 6.

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.

Red Hat Enterprise MRG (Messaging, Realtime, and Grid) is a next-generation IT infrastructure for enterprise computing. MRG offers increased performance, reliability, interoperability, and faster computing for enterprise customers.

MRG Grid provides high-throughput computing and enables enterprises to achieve higher peak computing capacity as well as improved infrastructure utilization by leveraging their existing technology to build high performance grids. MRG Grid provides a job-queueing mechanism, scheduling policy, and a priority scheme, as well as resource monitoring and resource management. Users submit their jobs to MRG Grid, where they are placed into a queue. MRG Grid then chooses when and where to run the jobs based upon a policy, carefully monitors their progress, and ultimately informs the user upon completion.

It was found that, when using RubyGems, the connection could be redirected from HTTPS to HTTP. This could lead to a user believing they are installing a gem via HTTPS, when the connection may have been silently downgraded to HTTP. (CVE-2012-2125)

It was found that RubyGems did not verify SSL connections. This could lead to man-in-the-middle attacks. (CVE-2012-2126)

It was discovered that the rubygems API validated version strings using an unsafe regular expression. An application making use of this API to process a version string from an untrusted source could be vulnerable to a denial of service attack through CPU exhaustion.
(CVE-2013-4287)

A flaw was found in the way cumin enforced user roles, allowing an unprivileged cumin user to access a range of resources without having the appropriate role. A remote, authenticated attacker could use this flaw to access privileged information, and perform a variety of privileged operations. (CVE-2013-4404)

It was found that multiple forms in the cumin web interface did not protect against Cross-Site Request Forgery (CSRF) attacks. If a remote attacker could trick a user, who is logged into the cumin web interface, into visiting a specially crafted URL, the attacker could perform actions in the context of the logged in user. (CVE-2013-4405)

It was found that cumin did not properly escape input from the 'Max allowance' field in the 'Set limit' form of the cumin web interface. A remote attacker could use this flaw to perform cross-site scripting (XSS) attacks against victims by tricking them into visiting a specially crafted URL. (CVE-2013-4414)

A flaw was found in the way cumin parsed POST request data. A remote attacker could potentially use this flaw to perform SQL injection attacks on cumin's database. (CVE-2013-4461)

Red Hat would like to thank Rubygems upstream for reporting CVE-2013-4287. Upstream acknowledges Damir Sharipov as the original reporter of CVE-2013-4287. The CVE-2013-4404, CVE-2013-4405, CVE-2013-4414, and CVE-2013-4461 issues were discovered by Tomas Novacik of the Red Hat MRG Quality Engineering team.

All users of the Grid capabilities of Red Hat Enterprise MRG are advised to upgrade to these updated packages, which correct these issues.

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)
