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.

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-2014-8090 2 Redhat, Ruby-lang 3 Enterprise Linux, Rhel Software Collections, Ruby 2025-04-12 N/A
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-2015-7551 3 Apple, Redhat, Ruby-lang 3 Mac Os X, Rhel Software Collections, Ruby 2025-04-12 N/A

NOTE: this vulnerability exists because of a CVE-2009-5147 regression.
CVE-2012-5380 1 Ruby-lang 1 Ruby 2025-04-11 6.7 Medium
Untrusted search path vulnerability in the installation functionality in Ruby 1.9.3-p194, when installed in the top-level C:\ directory, might allow local users to gain privileges via a Trojan horse DLL in the C:\Ruby193\bin directory, which may be added to the PATH system environment variable by an administrator, as demonstrated by a Trojan horse wlbsctrl.dll file used by the "IKE and AuthIP IPsec Keying Modules" system service in Windows Vista SP1, Windows Server 2008 SP2, Windows 7 SP1, and Windows 8 Release Preview. NOTE: CVE disputes this issue because the unsafe PATH is established only by a separate administrative action that is not a default part of the Ruby installation
CVE-2012-4522 2 Redhat, Ruby-lang 3 Enterprise Linux, Openshift, Ruby 2025-04-11 N/A
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-2012-5371 2 Redhat, Ruby-lang 2 Openshift, Ruby 2025-04-11 N/A
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-2013-4363 2 Ruby-lang, Rubygems 2 Ruby, Rubygems 2025-04-11 N/A
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-2013-0175 3 Erik Michaels-ober, Grape Project, Ruby-lang 3 Multi Xml, Grape, Ruby 2025-04-11 N/A
multi_xml gem 0.5.2 for Ruby, as used in Grape before 0.2.6 and possibly other products, does not properly restrict casts of string values, which allows remote attackers to conduct object-injection attacks and execute arbitrary code, or cause a denial of service (memory and CPU consumption) involving nested XML entity references, by leveraging support for (1) YAML type conversion or (2) Symbol type conversion, a similar vulnerability to CVE-2013-0156.
CVE-2011-1005 2 Redhat, Ruby-lang 2 Enterprise Linux, Ruby 2025-04-11 N/A
The safe-level feature in Ruby 1.8.6 through 1.8.6-420, 1.8.7 through 1.8.7-330, and 1.8.8dev allows context-dependent attackers to modify strings via the Exception#to_s method, as demonstrated by changing an intended pathname.
CVE-2012-4481 2 Redhat, Ruby-lang 2 Enterprise Linux, Ruby 2025-04-11 N/A
The safe-level feature in Ruby 1.8.7 allows context-dependent attackers to modify strings via the NameError#to_s method when operating on Ruby objects. NOTE: this issue is due to an incomplete fix for CVE-2011-1005.
CVE-2012-4466 2 Redhat, Ruby-lang 2 Openshift, Ruby 2025-04-11 N/A
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-2011-3009 2 Redhat, Ruby-lang 2 Enterprise Linux, Ruby 2025-04-11 N/A
Ruby before 1.8.6-p114 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, a related issue to CVE-2003-0900.
CVE-2012-4464 2 Redhat, Ruby-lang 2 Openshift, Ruby 2025-04-11 N/A
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-2011-1004 2 Redhat, Ruby-lang 2 Enterprise Linux, Ruby 2025-04-11 N/A

CVE-2013-4136 3 Phusion, Redhat, Ruby-lang 3 Passenger, Openshift, Ruby 2025-04-11 N/A
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/.
CVE-2013-1948 2 Rob Westgeest, Ruby-lang 2 Md2pdf, Ruby 2025-04-11 N/A
converter.rb in the md2pdf gem 0.0.1 for Ruby allows context-dependent attackers to execute arbitrary commands via shell metacharacters in a filename.
CVE-2011-2686 1 Ruby-lang 1 Ruby 2025-04-11 N/A
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, a related issue to CVE-2003-0900. NOTE: this issue exists because of a regression during Ruby 1.8.6 development.
CVE-2011-0188 3 Apple, Redhat, Ruby-lang 4 Mac Os X, Mac Os X Server, Enterprise Linux and 1 more 2025-04-11 N/A
The VpMemAlloc function in bigdecimal.c in the BigDecimal class in Ruby 1.9.2-p136 and earlier, as used on Apple Mac OS X before 10.6.7 and other platforms, does not properly allocate memory, which allows context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via vectors involving creation of a large BigDecimal value within a 64-bit process, related to an "integer truncation issue."
