CVE-2008-1891 1 Ruby-lang 1 Ruby 2026-04-23 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-2007-5770 2 Redhat, Ruby-lang 2 Enterprise Linux, Ruby 2026-04-23 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-2008-3657 2 Redhat, Ruby-lang 2 Enterprise Linux, Ruby 2026-04-23 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-2024-27280 2 Redhat, Ruby-lang 2 Enterprise Linux, Ruby 2026-04-15 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-2023-28756 4 Debian, Fedoraproject, Redhat and 1 more 6 Debian Linux, Fedora, Enterprise Linux and 3 more 2025-11-04 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 4 Apple, Debian, Redhat and 1 more 5 Macos, Debian Linux, Enterprise Linux and 2 more 2025-11-04 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 3 Fedoraproject, Redhat, Ruby-lang 6 Fedora, Enterprise Linux, Rhel Eus and 3 more 2025-11-04 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 2 Redhat, Ruby-lang 3 Enterprise Linux, Cgi, Ruby 2025-11-04 4 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 4 Netapp, Redhat, Ruby and 1 more 9 Ontap Tools, Enterprise Linux, Rhel Aus and 6 more 2025-11-04 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 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-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-2017-14033 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-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-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-2017-9225 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-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-2017-6181 1 Ruby-lang 1 Ruby 2025-04-20 N/A
The parse_char_class function in regparse.c in the Onigmo (aka Oniguruma-mod) regular expression library, as used in Ruby 2.4.0, allows remote attackers to cause a denial of service (deep recursion and application crash) via a crafted regular expression.
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.
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.
