CVE-2017-11465 1 Ruby-lang 1 Ruby 2025-04-20 N/A
The parser_yyerror function in the UTF-8 parser in Ruby 2.4.1 allows attackers to cause a denial of service (invalid write or read) or possibly have unspecified other impact via a crafted Ruby script, related to the parser_tokadd_utf8 function in parse.y. NOTE: this might have security relevance as a bypass of a $SAFE protection mechanism.
CVE-2016-2339 1 Ruby-lang 1 Ruby 2025-04-20 N/A
An exploitable heap overflow vulnerability exists in the Fiddle::Function.new "initialize" function functionality of Ruby. In Fiddle::Function.new "initialize" heap buffer "arg_types" allocation is made based on args array length. Specially constructed object passed as element of args array can increase this array size after mentioned allocation and cause heap overflow.
CVE-2016-2336 1 Ruby-lang 1 Ruby 2025-04-20 N/A
Type confusion exists in two methods of Ruby's WIN32OLE class, ole_invoke and ole_query_interface. Attacker passing different type of object than this assumed by developers can cause arbitrary code execution.
CVE-2009-5147 2 Redhat, Ruby-lang 2 Rhel Software Collections, Ruby 2025-04-20 N/A
DL::dlopen in Ruby 1.8, 1.9.0, 1.9.2, 1.9.3, 2.0.0 before patchlevel 648, and 2.1 before 2.1.8 opens libraries with tainted names.
CVE-2016-2337 1 Ruby-lang 1 Ruby 2025-04-20 N/A
Type confusion exists in _cancel_eval Ruby's TclTkIp class method. Attacker passing different type of object than String as "retval" argument can cause arbitrary code execution.
CVE-2014-2734 1 Ruby-lang 1 Ruby 2025-04-12 N/A
The openssl extension in Ruby 2.x does not properly maintain the state of process memory after a file is reopened, which allows remote attackers to spoof signatures within the context of a Ruby script that attempts signature verification after performing a certain sequence of filesystem operations. NOTE: this issue has been disputed by the Ruby OpenSSL team and third parties, who state that the original demonstration PoC contains errors and redundant or unnecessarily-complex code that does not appear to be related to a demonstration of the issue. As of 20140502, CVE is not aware of any public comment by the original researcher
CVE-2015-3900 4 Oracle, Redhat, Ruby-lang and 1 more 5 Solaris, Enterprise Linux, Rhel Software Collections and 2 more 2025-04-12 N/A
RubyGems 2.0.x before 2.0.16, 2.2.x before 2.2.4, and 2.4.x before 2.4.7 does not validate the hostname when fetching gems or making API requests, which allows remote attackers to redirect requests to arbitrary domains via a crafted DNS SRV record, aka a "DNS hijack attack."
CVE-2013-4413 2 Ruby-lang, Schneems 2 Ruby, Wicked 2025-04-12 N/A
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.
CVE-2015-7551 3 Apple, Redhat, Ruby-lang 3 Mac Os X, Rhel Software Collections, Ruby 2025-04-12 N/A
The Fiddle::Handle implementation in ext/fiddle/handle.c in Ruby before 2.0.0-p648, 2.1 before 2.1.8, and 2.2 before 2.2.4, as distributed in Apple OS X before 10.11.4 and other products, mishandles tainting, which allows context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted string, related to the DL module and the libffi library. NOTE: this vulnerability exists because of a CVE-2009-5147 regression.
CVE-2014-8080 4 Canonical, Opensuse, Redhat and 1 more 5 Ubuntu Linux, Opensuse, Enterprise Linux and 2 more 2025-04-12 N/A
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-2014-4975 4 Canonical, Debian, Redhat and 1 more 9 Ubuntu Linux, Debian Linux, Enterprise Linux and 6 more 2025-04-12 N/A
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-2014-8090 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-2013-2065 2 Opensuse, Ruby-lang 2 Opensuse, Ruby 2025-04-11 N/A
(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-2013-5647 2 Adam Zaninovich, Ruby-lang 2 Sounder, Ruby 2025-04-11 N/A
lib/sounder/sound.rb in the sounder gem 1.0.1 for Ruby allows remote 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-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-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-2012-4522 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-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-2013-1911 2 Mark Burns, Ruby-lang 2 Ldoce, Ruby 2025-04-11 N/A
lib/ldoce/word.rb in the ldoce 0.0.2 gem for Ruby allows remote attackers to execute arbitrary commands via shell metacharacters in (1) an mp3 URL or (2) file name.
