|---|---|---|---|---|---|
| CVE-2007-5770 | 1 Ruby-lang | 1 Ruby | 2026-04-23 | 5.0 MEDIUM | N/A |
| The (1) Net::ftptls, (2) Net::telnets, (3) Net::imap, (4) Net::pop, and (5) Net::smtp libraries in Ruby 1.8.5 and 1.8.6 do not verify that the commonName (CN) field in a server certificate matches the domain name in a request sent over SSL, which makes it easier for remote attackers to intercept SSL transmissions via a man-in-the-middle attack or spoofed web site, different components than CVE-2007-5162. | |||||
| CVE-2009-0642 | 1 Ruby-lang | 1 Ruby | 2026-04-23 | 6.8 MEDIUM | N/A |
| ext/openssl/ossl_ocsp.c in Ruby 1.8 and 1.9 does not properly check the return value from the OCSP_basic_verify function, which might allow remote attackers to successfully present an invalid X.509 certificate, possibly involving a revoked certificate. | |||||
| CVE-2008-3905 | 1 Ruby-lang | 1 Ruby | 2026-04-23 | 5.8 MEDIUM | N/A |
| resolv.rb in Ruby 1.8.5 and earlier, 1.8.6 before 1.8.6-p287, 1.8.7 before 1.8.7-p72, and 1.9 r18423 and earlier uses sequential transaction IDs and constant source ports for DNS requests, which makes it easier for remote attackers to spoof DNS responses, a different vulnerability than CVE-2008-1447. | |||||
| CVE-2008-3790 | 1 Ruby-lang | 1 Ruby | 2026-04-23 | 5.0 MEDIUM | N/A |
| The REXML module in Ruby 1.8.6 through 1.8.6-p287, 1.8.7 through 1.8.7-p72, and 1.9 allows context-dependent attackers to cause a denial of service (CPU consumption) via an XML document with recursively nested entities, aka an "XML entity explosion." | |||||
| CVE-2008-2376 | 2 Redhat, Ruby-lang | 2 Fedora 8, Ruby | 2026-04-23 | 7.5 HIGH | N/A |
| Integer overflow in the rb_ary_fill function in array.c in Ruby before revision 17756 allows context-dependent attackers to cause a denial of service (crash) or possibly have unspecified other impact via a call to the Array#fill method with a start (aka beg) argument greater than ARY_MAX_SIZE. NOTE: this issue exists because of an incomplete fix for other closely related integer overflows. | |||||
| CVE-2008-3657 | 1 Ruby-lang | 1 Ruby | 2026-04-23 | 7.5 HIGH | N/A |
| The dl module in Ruby 1.8.5 and earlier, 1.8.6 through 1.8.6-p286, 1.8.7 through 1.8.7-p71, and 1.9 through r18423 does not check "taintness" of inputs, which allows context-dependent attackers to bypass safe levels and execute dangerous functions by accessing a library using DL.dlopen. | |||||
| CVE-2009-4124 | 1 Ruby-lang | 1 Ruby | 2026-04-23 | 10.0 HIGH | N/A |
| Heap-based buffer overflow in the rb_str_justify function in string.c in Ruby 1.9.1 before 1.9.1-p376 allows context-dependent attackers to execute arbitrary code via unspecified vectors involving (1) String#ljust, (2) String#center, or (3) String#rjust. NOTE: some of these details are obtained from third party information. | |||||
| CVE-2008-4310 | 1 Ruby-lang | 1 Ruby | 2026-04-23 | 7.8 HIGH | N/A |
| httputils.rb in WEBrick in Ruby 1.8.1 and 1.8.5, as used in Red Hat Enterprise Linux 4 and 5, allows remote attackers to cause a denial of service (CPU consumption) via a crafted HTTP request. NOTE: this issue exists because of an incomplete fix for CVE-2008-3656. | |||||
| CVE-2008-2662 | 3 Canonical, Debian, Ruby-lang | 3 Ubuntu Linux, Debian Linux, Ruby | 2026-04-23 | 10.0 HIGH | N/A |
| Multiple integer overflows in the rb_str_buf_append function in Ruby 1.8.4 and earlier, 1.8.5 before 1.8.5-p231, 1.8.6 before 1.8.6-p230, 1.8.7 before 1.8.7-p22, and 1.9.0 before 1.9.0-2 allow context-dependent attackers to execute arbitrary code or cause a denial of service via unknown vectors that trigger memory corruption, a different issue than CVE-2008-2663, CVE-2008-2664, and CVE-2008-2725. NOTE: as of 20080624, there has been inconsistent usage of multiple CVE identifiers related to Ruby. This CVE description should be regarded as authoritative, although it is likely to change. | |||||
| CVE-2008-1891 | 1 Ruby-lang | 1 Ruby | 2026-04-23 | 5.0 MEDIUM | N/A |
| Directory traversal vulnerability in WEBrick in Ruby 1.8.4 and earlier, 1.8.5 before 1.8.5-p231, 1.8.6 before 1.8.6-p230, 1.8.7 before 1.8.7-p22, and 1.9.0 before 1.9.0-2, when using NTFS or FAT filesystems, allows remote attackers to read arbitrary CGI files via a trailing (1) + (plus), (2) %2b (encoded plus), (3) . (dot), (4) %2e (encoded dot), or (5) %20 (encoded space) character in the URI, possibly related to the WEBrick::HTTPServlet::FileHandler and WEBrick::HTTPServer.new functionality and the :DocumentRoot option. | |||||
| CVE-2007-5162 | 1 Ruby-lang | 1 Ruby | 2026-04-23 | 4.3 MEDIUM | N/A |
| The connect method in lib/net/http.rb in the (1) Net::HTTP and (2) Net::HTTPS libraries in Ruby 1.8.5 and 1.8.6 does not verify that the commonName (CN) field in a server certificate matches the domain name in an HTTPS request, which makes it easier for remote attackers to intercept SSL transmissions via a man-in-the-middle attack or spoofed web site. | |||||
| CVE-2009-4492 | 1 Ruby-lang | 2 Ruby, Webrick | 2026-04-23 | 7.5 HIGH | N/A |
| WEBrick 1.3.1 in Ruby 1.8.6 through patchlevel 383, 1.8.7 through patchlevel 248, 1.8.8dev, 1.9.1 through patchlevel 376, and 1.9.2dev writes data to a log file without sanitizing non-printable characters, which might allow remote attackers to modify a window's title, or possibly execute arbitrary commands or overwrite files, via an HTTP request containing an escape sequence for a terminal emulator. | |||||
| CVE-2023-28756 | 3 Debian, Fedoraproject, Ruby-lang | 4 Debian Linux, Fedora, Ruby and 1 more | 2025-11-04 | N/A | 5.3 MEDIUM |
| A ReDoS issue was discovered in the Time component through 0.2.1 in Ruby through 3.2.1. The Time parser mishandles invalid URLs that have specific characters. It causes an increase in execution time for parsing strings to Time objects. The fixed versions are 0.1.1 and 0.2.2. | |||||
| CVE-2022-28739 | 3 Apple, Debian, Ruby-lang | 3 Macos, Debian Linux, Ruby | 2025-11-04 | 4.3 MEDIUM | 7.5 HIGH |
| There is a buffer over-read in Ruby before 2.6.10, 2.7.x before 2.7.6, 3.x before 3.0.4, and 3.1.x before 3.1.2. It occurs in String-to-Float conversion, including Kernel#Float and String#to_f. | |||||
| CVE-2021-33621 | 2 Fedoraproject, Ruby-lang | 3 Fedora, Cgi, Ruby | 2025-11-04 | N/A | 8.8 HIGH |
| The cgi gem before 0.1.0.2, 0.2.x before 0.2.2, and 0.3.x before 0.3.5 for Ruby allows HTTP response splitting. This is relevant to applications that use untrusted user input either to generate an HTTP response or to create a CGI::Cookie object. | |||||
| CVE-2025-27220 | 1 Ruby-lang | 2 Cgi, Ruby | 2025-11-03 | N/A | 4.0 MEDIUM |
| In the CGI gem before 0.4.2 for Ruby, a Regular Expression Denial of Service (ReDoS) vulnerability exists in the Util#escapeElement method. | |||||
| CVE-2024-49761 | 2 Netapp, Ruby-lang | 3 Ontap Tools, Rexml, Ruby | 2025-11-03 | N/A | 7.5 HIGH |
| REXML is an XML toolkit for Ruby. The REXML gem before 3.3.9 has a ReDoS vulnerability when it parses an XML that has many digits between &# and x...; in a hex numeric character reference (&#x...;). This does not happen with Ruby 3.2 or later. Ruby 3.1 is the only affected maintained Ruby. The REXML gem 3.3.9 or later include the patch to fix the vulnerability. | |||||
| CVE-2021-41819 | 6 Debian, Fedoraproject, Opensuse and 3 more | 9 Debian Linux, Fedora, Factory and 6 more | 2025-05-22 | 5.0 MEDIUM | 7.5 HIGH |
| CGI::Cookie.parse in Ruby through 2.6.8 mishandles security prefixes in cookie names. This also affects the CGI gem through 0.3.0 for Ruby. | |||||
| CVE-2017-14064 | 4 Canonical, Debian, Redhat and 1 more | 9 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 6 more | 2025-04-20 | 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-2017-17790 | 1 Ruby-lang | 1 Ruby | 2025-04-20 | 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. | |||||
