CVE-2017-14033 2 Redhat, Ruby-lang 3 Enterprise Linux, Rhel Software Collections, Ruby 2025-04-20 N/A
The decode method in the OpenSSL::ASN1 module in Ruby before 2.2.8, 2.3.x before 2.3.5, and 2.4.x through 2.4.1 allows attackers to cause a denial of service (interpreter crash) via a crafted string.
CVE-2017-10784 2 Redhat, Ruby-lang 3 Enterprise Linux, Rhel Software Collections, Ruby 2025-04-20 N/A
The Basic authentication code in WEBrick library in Ruby before 2.2.8, 2.3.x before 2.3.5, and 2.4.x through 2.4.1 allows remote attackers to inject terminal emulator escape sequences into its log and possibly execute arbitrary commands via a crafted user name.
CVE-2017-0898 2 Redhat, Ruby-lang 3 Enterprise Linux, Rhel Software Collections, Ruby 2025-04-20 N/A
Ruby before 2.4.2, 2.3.5, and 2.2.8 is vulnerable to a malicious format string which contains a precious specifier (*) with a huge minus value. Such situation can lead to a buffer overrun, resulting in a heap memory corruption or an information disclosure from the heap.
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-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-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-2013-4413 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-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-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-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.
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-2010-2489 2 Microsoft, Ruby-lang 2 Windows, Ruby 2025-04-11 N/A
Buffer overflow in Ruby 1.9.x before 1.9.1-p429 on Windows might allow local users to gain privileges via a crafted ARGF.inplace_mode value that is not properly handled when constructing the filenames of the backup files.
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-2013-1821 2 Redhat, Ruby-lang 5 Enterprise Linux, Fuse Esb Enterprise, Jboss Enterprise Soa Platform and 2 more 2025-04-11 N/A
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.
CVE-2013-4287 3 Redhat, Ruby-lang, Rubygems 7 Enterprise Linux, Enterprise Mrg, Openshift and 4 more 2025-04-11 N/A
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-2011-1004 2 Redhat, Ruby-lang 2 Enterprise Linux, Ruby 2025-04-11 N/A
The FileUtils.remove_entry_secure method in Ruby 1.8.6 through 1.8.6-420, 1.8.7 through 1.8.7-330, 1.8.8dev, 1.9.1 through 1.9.1-430, 1.9.2 through 1.9.2-136, and 1.9.3dev allows local users to delete arbitrary files via a symlink attack.
