CVSS: 9.1EPSS: 1%CPEs: 15EXPL: 2CVE-2017-0898 – ruby: Buffer underrun vulnerability in Kernel.sprintf
https://notcve.org/view.php?id=CVE-2017-0898
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. Ruby, en versiones anteriores a la 2.4.2, 2.3.5 y 2.2.8, es vulnerable a una cadena de formato maliciosa qe contiene un especificador (*) con un valor grande negativo. Esta situación puede provocar un desbordamiento de búfer, provocando una corrupción de la memoria dinámica (heap) o una fuga de información de dicha memoria dinámica. A buffer underflow was found in ruby's sprintf function. • http://www.securityfocus.com/bid/100862 http://www.securitytracker.com/id/1039363 https://access.redhat.com/errata/RHSA-2017:3485 https://access.redhat.com/errata/RHSA-2018:0378 https://access.redhat.com/errata/RHSA-2018:0583 https://access.redhat.com/errata/RHSA-2018:0585 https://github.com/mruby/mruby/issues/3722 https://hackerone.com/reports/212241 https://lists.debian.org/debian-lts-announce/2018/07/msg00012.html https://security.gentoo.org/glsa/201710-18 https:/ • CWE-122: Heap-based Buffer Overflow CWE-134: Use of Externally-Controlled Format String •

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. El método URI.decode_www_form_component en versiones de Ruby anteriores a la 1.9.2-p330 permite que atacantes remotos provoquen una denegación de servicio (expresión regular catastrófica, consumo de recursos o bloqueo de la aplicación) utilizando un string manipulado. • http://www.openwall.com/lists/oss-security/2015/07/13/6 http://www.securitytracker.com/id/1032874 https://github.com/ruby/www.ruby-lang.org/issues/817 https://www.ruby-lang.org/en/news/2014/08/19/ruby-1-9-2-p330-released • CWE-399: Resource Management Errors •
CVSS: 9.8EPSS: 0%CPEs: 29EXPL: 1CVE-2017-14064 – ruby: Arbitrary heap exposure during a JSON.generate call
https://notcve.org/view.php?id=CVE-2017-14064
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. Ruby hasta la versión 2.2.7, 2.3.x hasta la 2.3.4, y 2.4.x hasta la 2.4.1 puede exponer memoria arbitraria durante una llamada JSON.generate. Los problemas surgen al usar strdup en ext/json/ext/generator/generator.c, el cual se detendría después de encontrar un byte '\0', devolviendo un puntero a un string de longitud cero, que no es la longitud almacenada en space_len. A buffer overflow vulnerability was found in the JSON extension of ruby. • http://www.securityfocus.com/bid/100890 http://www.securitytracker.com/id/1039363 http://www.securitytracker.com/id/1042004 https://access.redhat.com/errata/RHSA-2017:3485 https://access.redhat.com/errata/RHSA-2018:0378 https://access.redhat.com/errata/RHSA-2018:0583 https://access.redhat.com/errata/RHSA-2018:0585 https://bugs.ruby-lang.org/issues/13853 https://github.com/flori/json/commit/8f782fd8e181d9cfe9387ded43a5ca9692266b85 https://hackerone.com/reports/209949 https://lists. • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

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. El modulo Net::SMTP de Ruby anterior a su versión 2.4.0 es vulnerable a la inyección de comandos SMTP mediante secuencias CRLF de los comandos "RCPT TO" o "MAIL FROM", como demuestra las secuencias CRLF inmediatamente antes y después de la substring DATA. • http://www.mbsd.jp/Whitepaper/smtpi.pdf https://github.com/ruby/ruby/commit/0827a7e52ba3d957a634b063bf5a391239b9ffee https://github.com/rubysec/ruby-advisory-db/issues/215 https://hackerone.com/reports/137631 https://lists.debian.org/debian-lts-announce/2018/07/msg00012.html https://www.debian.org/security/2017/dsa-3966 • CWE-93: Improper Neutralization of CRLF Sequences ('CRLF Injection') •

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. Se descubrió un problema en Oniguruma versión 6.2.0, tal como es usado en Oniguruma-mod en Ruby hasta la versión 2.4.1 y mbstring en PHP hasta la versión 7.1.5. • https://github.com/kkos/oniguruma/commit/166a6c3999bf06b4de0ab4ce6b088a468cc4029f https://github.com/kkos/oniguruma/issues/56 • CWE-787: Out-of-bounds Write •
