CVE-2025-58767 | 2 Ruby, Ruby-lang | 2 Rexml, Rexml | 2025-09-19 | 7.5 High |
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 | 2025-05-03 | 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-2017-9225 | 3 Oniguruma Project, Php, Ruby-lang | 3 Oniguruma, Php, Ruby | 2025-04-20 | N/A |
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 stack out-of-bounds write in onigenc_unicode_get_case_fold_codes_by_str() occurs during regular expression compilation. Code point 0xFFFFFFFF is not properly handled in unicode_unfold_key(). A malformed regular expression could result in 4 bytes being written off the end of a stack buffer of expand_case_fold_string() during the call to onigenc_unicode_get_case_fold_codes_by_str(), a typical stack buffer overflow. | ||||
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. | ||||
CVE-2015-9096 | 1 Ruby-lang | 1 Ruby | 2025-04-20 | 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-2009-5147 | 2 Redhat, Ruby-lang | 2 Rhel Software Collections, Ruby | 2025-04-20 | N/A |
DL::dlopen in Ruby 1.8, 1.9.0, 1.9.2, 1.9.3, 2.0.0 before patchlevel 648, and 2.1 before 2.1.8 opens libraries with tainted names. | ||||
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-2017-9229 | 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-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-2017-0898 | 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-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-2017-14064 | 4 Canonical, Debian, Redhat and 1 more | 11 Ubuntu Linux, Debian Linux, Enterprise Linux and 8 more | 2025-04-20 | 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-2017-10784 | 2 Redhat, Ruby-lang | 3 Enterprise Linux, Rhel Software Collections, Ruby | 2025-04-20 | 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. |
