|---|---|---|---|---|---|
| CVE-2017-17790 | 1 Ruby-lang | 1 Ruby | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| The lazy_initialize function in lib/resolv.rb in Ruby through 2.4.3 uses Kernel#open, which might allow Command Injection attacks, as demonstrated by a Resolv::Hosts::new argument beginning with a '|' character, a different vulnerability than CVE-2017-17405. NOTE: situations with untrusted input may be highly unlikely. | |||||
| CVE-2017-17742 | 2 Debian, Ruby-lang | 2 Debian Linux, Ruby | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1 allows an HTTP Response Splitting attack. An attacker can inject a crafted key and value into an HTTP response for the HTTP server of WEBrick. | |||||
| CVE-2017-17405 | 3 Debian, Redhat, Ruby-lang | 8 Debian Linux, Enterprise Linux Desktop, Enterprise Linux Server and 5 more | 2024-11-21 | 9.3 HIGH | 8.8 HIGH |
| Ruby before 2.4.3 allows Net::FTP command injection. Net::FTP#get, getbinaryfile, gettextfile, put, putbinaryfile, and puttextfile use Kernel#open to open a local file. If the localfile argument starts with the "|" pipe character, the command following the pipe character is executed. The default value of localfile is File.basename(remotefile), so malicious FTP servers could cause arbitrary command execution. | |||||
| CVE-2017-14064 | 4 Canonical, Debian, Redhat and 1 more | 9 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 6 more | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| 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 | 1 Ruby-lang | 1 Ruby | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| 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 | 7.5 HIGH | 9.8 CRITICAL |
| 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 | 1 Ruby-lang | 1 Ruby | 2024-11-21 | 9.3 HIGH | 8.8 HIGH |
| 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 | 1 Ruby-lang | 1 Ruby | 2024-11-21 | 6.4 MEDIUM | 9.1 CRITICAL |
| 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 | 5.0 MEDIUM | 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 | 7.5 HIGH | 9.8 CRITICAL |
| 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-2016-2337 | 1 Ruby-lang | 1 Ruby | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| 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 | 7.5 HIGH | 9.8 CRITICAL |
| 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 | 4.3 MEDIUM | 6.1 MEDIUM |
| 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 | 2 Apple, Ruby-lang | 2 Mac Os X, Ruby | 2024-11-21 | 4.6 MEDIUM | 8.4 HIGH |
| 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 | 4 Solaris, Enterprise Linux, Ruby and 1 more | 2024-11-21 | 5.0 MEDIUM | 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 | 4.3 MEDIUM | 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 | 1 Ruby-lang | 1 Ruby | 2024-11-21 | 5.0 MEDIUM | 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 | 4 Ubuntu Linux, Opensuse, Enterprise Linux and 1 more | 2024-11-21 | 5.0 MEDIUM | 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 | 5.0 MEDIUM | 7.5 HIGH |
| 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 | 7 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 4 more | 2024-11-21 | 5.0 MEDIUM | 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. | |||||
