CVE-2017-14064 4 Canonical, Debian, Redhat and 1 more 11 Ubuntu Linux, Debian Linux, Enterprise Linux and 8 more 2024-11-21 N/A
Ruby through 2.2.7, 2.3.x through 2.3.4, and 2.4.x through 2.4.1 can expose arbitrary memory during a JSON.generate call. The issues lies in using strdup in ext/json/ext/generator/generator.c, which will stop after encountering a '\0' byte, returning a pointer to a string of length zero, which is not the length stored in space_len.
CVE-2017-14033 2 Redhat, Ruby-lang 3 Enterprise Linux, Rhel Software Collections, Ruby 2024-11-21 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-2017-11465 1 Ruby-lang 1 Ruby 2024-11-21 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-2017-10784 2 Redhat, Ruby-lang 3 Enterprise Linux, Rhel Software Collections, Ruby 2024-11-21 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 2024-11-21 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-2016-7798 2 Debian, Ruby-lang 2 Debian Linux, Openssl 2024-11-21 7.5 High
The openssl gem for Ruby uses the same initialization vector (IV) in GCM Mode (aes-*-gcm) when the IV is set before the key, which makes it easier for context-dependent attackers to bypass the encryption protection mechanism.
CVE-2016-2339 1 Ruby-lang 1 Ruby 2024-11-21 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-2016-2338 2 Debian, Ruby-lang 2 Debian Linux, Ruby 2024-11-21 9.8 Critical
An exploitable heap overflow vulnerability exists in the Psych::Emitter start_document function of Ruby. In Psych::Emitter start_document function heap buffer "head" allocation is made based on tags array length. Specially constructed object passed as element of tags array can increase this array size after mentioned allocation and cause heap overflow.
CVE-2016-2337 1 Ruby-lang 1 Ruby 2024-11-21 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-2016-2336 1 Ruby-lang 1 Ruby 2024-11-21 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-2015-9096 1 Ruby-lang 1 Ruby 2024-11-21 N/A
Net::SMTP in Ruby before 2.4.0 is vulnerable to SMTP command injection via CRLF sequences in a RCPT TO or MAIL FROM command, as demonstrated by CRLF sequences immediately before and after a DATA substring.
CVE-2015-7551 3 Apple, Redhat, Ruby-lang 3 Mac Os X, Rhel Software Collections, Ruby 2024-11-21 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 2024-11-21 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-2015-1855 3 Debian, Puppet, Ruby-lang 5 Debian Linux, Puppet Agent, Puppet Enterprise and 2 more 2024-11-21 5.9 Medium
verify_certificate_identity in the OpenSSL extension in Ruby before 2.0.0 patchlevel 645, 2.1.x before 2.1.6, and 2.2.x before 2.2.2 does not properly validate hostnames, which allows remote attackers to spoof servers via vectors related to (1) multiple wildcards, (1) wildcards in IDNA names, (3) case sensitivity, and (4) non-ASCII characters.
CVE-2014-8090 2 Redhat, Ruby-lang 3 Enterprise Linux, Rhel Software Collections, Ruby 2024-11-21 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-2014-8080 4 Canonical, Opensuse, Redhat and 1 more 5 Ubuntu Linux, Opensuse, Enterprise Linux and 2 more 2024-11-21 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-2014-6438 1 Ruby-lang 1 Ruby 2024-11-21 N/A
The URI.decode_www_form_component method in Ruby before 1.9.2-p330 allows remote attackers to cause a denial of service (catastrophic regular expression backtracking, resource consumption, or application crash) via a crafted string.
CVE-2014-4975 4 Canonical, Debian, Redhat and 1 more 9 Ubuntu Linux, Debian Linux, Enterprise Linux and 6 more 2024-11-21 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-2014-2734 1 Ruby-lang 1 Ruby 2024-11-21 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-2013-5647 2 Adam Zaninovich, Ruby-lang 2 Sounder, Ruby 2024-11-21 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.
