| CVE-2019-16255 | 4 Debian, Opensuse, Oracle and 1 more | 4 Debian Linux, Leap, Graalvm and 1 more | 2026-06-17 | 6.8 MEDIUM | 8.1 HIGH |
| Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 allows code injection if the first argument (aka the "command" argument) to Shell#[] or Shell#test in lib/shell.rb is untrusted data. An attacker can exploit this to call an arbitrary Ruby method. | |||||
| CVE-2019-16254 | 2 Debian, Ruby-lang | 2 Debian Linux, Ruby | 2026-06-17 | 5.0 MEDIUM | 5.3 MEDIUM |
| Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 allows HTTP Response Splitting. If a program using WEBrick inserts untrusted input into the response header, an attacker can exploit it to insert a newline character to split a header, and inject malicious content to deceive clients. NOTE: this issue exists because of an incomplete fix for CVE-2017-17742, which addressed the CRLF vector, but did not address an isolated CR or an isolated LF. | |||||

| CVE-2018-16396 | 4 Canonical, Debian, Redhat and 1 more | 4 Ubuntu Linux, Debian Linux, Enterprise Linux and 1 more | 2026-06-17 | 6.8 MEDIUM | 8.1 HIGH |
| 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. | |||||
| CVE-2018-16395 | 4 Canonical, Debian, Redhat and 1 more | 5 Ubuntu Linux, Debian Linux, Enterprise Linux and 2 more | 2026-06-17 | 7.5 HIGH | 9.8 CRITICAL |
| 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 leveraged to create an illegitimate certificate that may be accepted as legitimate and then used in signing or encryption operations. | |||||
| CVE-2017-9229 | 3 Oniguruma Project, Php, Ruby-lang | 3 Oniguruma, Php, Ruby | 2026-06-17 | 5.0 MEDIUM | 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-2017-9225 | 3 Oniguruma Project, Php, Ruby-lang | 3 Oniguruma, Php, Ruby | 2026-06-17 | 7.5 HIGH | 9.8 CRITICAL |
| 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-2017-6181 | 1 Ruby-lang | 1 Ruby | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2017-17790 | 1 Ruby-lang | 1 Ruby | 2026-06-17 | 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. | |||||
| CVE-2017-17742 | 2 Debian, Ruby-lang | 2 Debian Linux, Ruby | 2026-06-17 | 5.0 MEDIUM | 5.3 MEDIUM |
| 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. | |||||
| CVE-2017-17405 | 3 Debian, Redhat, Ruby-lang | 8 Debian Linux, Enterprise Linux Desktop, Enterprise Linux Server and 5 more | 2026-06-17 | 9.3 HIGH | 8.8 HIGH |
| 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-2017-14064 | 4 Canonical, Debian, Redhat and 1 more | 9 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 6 more | 2026-06-17 | 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-2017-14033 | 1 Ruby-lang | 1 Ruby | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2017-11465 | 1 Ruby-lang | 1 Ruby | 2026-06-17 | 7.5 HIGH | 9.8 CRITICAL |
| 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. | |||||
