|---|---|---|---|---|---|---|
| CVE-2011-4121 | The OpenSSL extension of Ruby (Git trunk) versions after 2011-09-01 up to 2011-11-03 always generated an exponent value of '1' to be used for private RSA key generation. A remote attacker could use this flaw to bypass or corrupt integrity of services, depending on strong private RSA keys generation mechanism. | [email protected] | 9.8 | 2.53% | 2019-11-26 | 2026-06-16 |
| CVE-2011-3624 | Various methods in WEBrick::HTTPRequest in Ruby 1.9.2 and 1.8.7 and earlier do not validate the X-Forwarded-For, X-Forwarded-Host and X-Forwarded-Server headers in requests, which might allow remote attackers to inject arbitrary text into log files or bypass intended address parsing via a crafted header. | [email protected] | 5.3 | 1.52% | 2019-11-25 | 2026-06-16 |
| CVE-2018-16396 | An issue was discovered in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. It does not taint strings that result from unpacking tainted strings with some formats. | [email protected] | 8.1 | 7.97% | 2018-11-16 | 2026-06-16 |
| CVE-2018-16395 | An issue was discovered in the OpenSSL library in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. When two OpenSSL::X509::Name objects are compared using ==, depending on the ordering, non-equal objects may return true. When the first argument is one character longer than the second, or the second argument contains a character that is one less than a character in the same position of the first argument, the result of == will be true. This could be leve | [email protected] | 9.8 | 10.71% | 2018-11-16 | 2026-06-16 |

When using the corresponding method, unintentional directory traversal may be performed. | [email protected] | 9.1 | 10.10% | 2018-04-03 | 2026-06-16 |
| CVE-2018-8779 | In 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, the UNIXServer.open and UNIXSocket.open methods are not checked for null characters. It may be connected to an unintended socket. | [email protected] | 7.5 | 7.17% | 2018-04-03 | 2026-06-16 |
| CVE-2018-8778 | In 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, an attacker controlling the unpacking format (similar to format string vulnerabilities) can trigger a buffer under-read in the String#unpack method, resulting in a massive and controlled information disclosure. | [email protected] | 7.5 | 7.83% | 2018-04-03 | 2026-06-16 |
| CVE-2018-8777 | In 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, an attacker can pass a large HTTP request with a crafted header to WEBrick server or a crafted body to WEBrick server/handler and cause a denial of service (memory consumption). | [email protected] | 7.5 | 4.64% | 2018-04-03 | 2026-06-16 |
| CVE-2018-6914 | Directory traversal vulnerability in the Dir.mktmpdir method in the tmpdir library in 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 might allow attackers to create arbitrary directories or files via a .. (dot dot) in the prefix argument. | [email protected] | 7.5 | 10.55% | 2018-04-03 | 2026-06-16 |
| CVE-2017-17742 | 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. | [email protected] | 5.3 | 5.76% | 2018-04-03 | 2026-06-16 |
| CVE-2017-17790 | 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. | [email protected] | 9.8 | 5.91% | 2017-12-20 | 2026-06-16 |
| CVE-2017-17405 | 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. | [email protected] | 8.8 | 73.93% | 2017-12-15 | 2026-06-16 |
| CVE-2017-14033 | 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. | [email protected] | 7.5 | 7.73% | 2017-09-19 | 2026-06-16 |
| CVE-2017-10784 | 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. | [email protected] | 8.8 | 16.41% | 2017-09-19 | 2026-06-16 |
| CVE-2017-0898 | 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. | [email protected] | 9.1 | 9.72% | 2017-09-15 | 2026-06-16 |
| CVE-2014-6438 | 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. | [email protected] | 7.5 | 4.13% | 2017-09-06 | 2026-06-16 |
| CVE-2017-14064 | 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. | [email protected] | 9.8 | 9.45% | 2017-08-31 | 2026-06-16 |
| CVE-2017-11465 | 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. | [email protected] | 9.8 | 1.68% | 2017-07-19 | 2026-06-16 |
| CVE-2015-9096 | 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. | [email protected] | 6.1 | 3.65% | 2017-06-12 | 2026-06-16 |
| CVE-2017-9229 | An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A SIGSEGV occurs in left_adjust_char_head() during regular expression compilation. Invalid handling of reg->dmax in forward_search_range() could result in an invalid pointer dereference, normally as an immediate denial-of-service condition. | [email protected] | 7.5 | 5.13% | 2017-05-24 | 2026-06-16 |
