| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2014-03-11 | CVE-2013-4413 | Path Traversal vulnerability in Schneems Wicked Directory traversal vulnerability in controller/concerns/render_redirect.rb in the Wicked gem before 1.0.1 for Ruby allows remote attackers to read arbitrary files via a %2E%2E%2F (encoded dot dot slash) in the step. | 5.0 |
| 2013-11-23 | CVE-2013-4164 | Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in Ruby-Lang Ruby 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. | 6.8 |
| 2013-11-02 | CVE-2013-2065 | Permissions, Privileges, and Access Controls vulnerability in multiple products (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. | 6.4 |
| 2013-10-17 | CVE-2013-4363 | Cryptographic Issues vulnerability in multiple products 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. | 4.3 |
| 2013-10-17 | CVE-2013-4287 | Cryptographic Issues vulnerability in multiple products 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. | 4.3 |
| 2013-09-30 | CVE-2013-4136 | Link Following vulnerability in Phusion Passenger ext/common/ServerInstanceDir.h in Phusion Passenger gem before 4.0.6 for Ruby allows local users to gain privileges or possibly change the ownership of arbitrary directories via a symlink attack on a directory with a predictable name in /tmp/. | 4.4 |
| 2013-04-25 | CVE-2013-0233 | Resource Management Errors vulnerability in multiple products Devise gem 2.2.x before 2.2.3, 2.1.x before 2.1.3, 2.0.x before 2.0.5, and 1.5.x before 1.5.4 for Ruby, when using certain databases, does not properly perform type conversion when performing database queries, which might allow remote attackers to cause incorrect results to be returned and bypass security checks via unknown vectors, as demonstrated by resetting passwords of arbitrary accounts. | 6.8 |
| 2013-04-25 | CVE-2012-4466 | Permissions, Privileges, and Access Controls vulnerability in Ruby-Lang Ruby 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. | 5.0 |
| 2013-04-25 | CVE-2012-4464 | Permissions, Privileges, and Access Controls vulnerability in Ruby-Lang Ruby 1.9.3/2.0/2.0.0 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. | 5.0 |
| 2013-04-09 | CVE-2013-1821 | Improper Input Validation vulnerability in Ruby-Lang Ruby lib/rexml/text.rb in the REXML parser in Ruby before 1.9.3-p392 allows remote attackers to cause a denial of service (memory consumption and crash) via crafted text nodes in an XML document, aka an XML Entity Expansion (XEE) attack. | 5.0 |
