| CVE-2025-58767 | 2 Ruby, Ruby-lang | 2 Rexml, Rexml | 2025-09-30 | 5.3 Medium |
| REXML is an XML toolkit for Ruby. The REXML gems from 3.3.3 to 3.4.1 has a DoS vulnerability when parsing XML containing multiple XML declarations. If you need to parse untrusted XMLs, you may be impacted to these vulnerabilities. The REXML gem 3.4.2 or later include the patches to fix these vulnerabilities. | ||||
| CVE-2024-43398 | 3 Netapp, Redhat, Ruby-lang | 7 Bootstrap Os, Hci Compute Node, Enterprise Linux and 4 more | 2025-09-19 | 5.9 Medium |
| REXML is an XML toolkit for Ruby. The REXML gem before 3.3.6 has a DoS vulnerability when it parses an XML that has many deep elements that have same local name attributes. If you need to parse untrusted XMLs with tree parser API like REXML::Document.new, you may be impacted to this vulnerability. If you use other parser APIs such as stream parser API and SAX2 parser API, this vulnerability is not affected. The REXML gem 3.3.6 or later include the patch to fix the vulnerability. | ||||
| CVE-2024-39908 | 3 Netapp, Redhat, Ruby-lang | 4 Bootstrap Os, Hci Compute Node, Enterprise Linux and 1 more | 2025-09-19 | 4.3 Medium |
| REXML is an XML toolkit for Ruby. The REXML gem before 3.3.1 has some DoS vulnerabilities when it parses an XML that has many specific characters such as `<`, `0` and `%>`. If you need to parse untrusted XMLs, you many be impacted to these vulnerabilities. The REXML gem 3.3.2 or later include the patches to fix these vulnerabilities. Users are advised to upgrade. Users unable to upgrade should avoid parsing untrusted XML strings. | ||||
| CVE-2024-35176 | 2 Redhat, Ruby-lang | 2 Enterprise Linux, Rexml | 2025-09-19 | 5.3 Medium |
| REXML is an XML toolkit for Ruby. The REXML gem before 3.2.6 has a denial of service vulnerability when it parses an XML that has many `<`s in an attribute value. Those who need to parse untrusted XMLs may be impacted to this vulnerability. The REXML gem 3.2.7 or later include the patch to fix this vulnerability. As a workaround, don't parse untrusted XMLs. | ||||
| CVE-2025-6442 | 2 Ruby, Ruby-lang | 2 Webrick, Webrick | 2025-08-18 | 5.9 Medium |
| Ruby WEBrick read_header HTTP Request Smuggling Vulnerability. This vulnerability allows remote attackers to smuggle arbitrary HTTP requests on affected installations of Ruby WEBrick. This issue is exploitable when the product is deployed behind an HTTP proxy that fulfills specific conditions. The specific flaw exists within the read_headers method. The issue results from the inconsistent parsing of terminators of HTTP headers. An attacker can leverage this vulnerability to smuggle arbitrary HTTP requests. Was ZDI-CAN-21876. | ||||
| CVE-2025-27221 | 2 Redhat, Ruby-lang | 2 Enterprise Linux, Uri | 2025-08-01 | 3.2 Low |
| In the URI gem before 1.0.3 for Ruby, the URI handling methods (URI.join, URI#merge, URI#+) have an inadvertent leakage of authentication credentials because userinfo is retained even after changing the host. | ||||
| CVE-2021-41819 | 6 Debian, Fedoraproject, Opensuse and 3 more | 12 Debian Linux, Fedora, Factory and 9 more | 2025-05-22 | 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-2025-43857 | 1 Ruby-lang | 1 Net\ | 2025-05-12 | 7.5 High |
| Net::IMAP implements Internet Message Access Protocol (IMAP) client functionality in Ruby. Prior to versions 0.5.7, 0.4.20, 0.3.9, and 0.2.5, there is a possibility for denial of service by memory exhaustion when net-imap reads server responses. At any time while the client is connected, a malicious server can send can send a "literal" byte count, which is automatically read by the client's receiver thread. The response reader immediately allocates memory for the number of bytes indicated by the server response. This should not be an issue when securely connecting to trusted IMAP servers that are well-behaved. It can affect insecure connections and buggy, untrusted, or compromised servers (for example, connecting to a user supplied hostname). This issue has been patched in versions 0.5.7, 0.4.20, 0.3.9, and 0.2.5. | ||||
| CVE-2024-27280 | 2 Redhat, Ruby-lang | 2 Enterprise Linux, Ruby | 2025-05-02 | 9.8 Critical |
| A buffer-overread issue was discovered in StringIO 3.0.1, as distributed in Ruby 3.0.x through 3.0.6 and 3.1.x through 3.1.4. The ungetbyte and ungetc methods on a StringIO can read past the end of a string, and a subsequent call to StringIO.gets may return the memory value. 3.0.3 is the main fixed version; however, for Ruby 3.0 users, a fixed version is stringio 3.0.1.1, and for Ruby 3.1 users, a fixed version is stringio 3.0.1.2. | ||||
| CVE-2014-6438 | 1 Ruby-lang | 1 Ruby | 2025-04-20 | 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-2016-7798 | 2 Debian, Ruby-lang | 2 Debian Linux, Openssl | 2025-04-20 | 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-2017-9229 | 4 Oniguruma Project, Php, Redhat and 1 more | 4 Oniguruma, Php, Rhel Software Collections and 1 more | 2025-04-20 | 7.5 High |
| 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. | ||||
| CVE-2016-2336 | 1 Ruby-lang | 1 Ruby | 2025-04-20 | 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-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-2017-17790 | 2 Redhat, Ruby-lang | 3 Enterprise Linux, Rhel Software Collections, Ruby | 2025-04-20 | N/A |
| 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-2017-14033 | 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-2017-17405 | 3 Debian, Redhat, Ruby-lang | 13 Debian Linux, Enterprise Linux, Enterprise Linux Desktop and 10 more | 2025-04-20 | N/A |
| 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-2016-2339 | 1 Ruby-lang | 1 Ruby | 2025-04-20 | 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-2017-11465 | 1 Ruby-lang | 1 Ruby | 2025-04-20 | 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-2016-2337 | 1 Ruby-lang | 1 Ruby | 2025-04-20 | 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. | ||||
