In the yajl-ruby gem 1.3.0 for Ruby, when a crafted JSON file is supplied to Yajl::Parser.new.parse, the whole ruby process crashes with a SIGABRT in the yajl_string_decode function in yajl_encode.c. This results in the whole ruby process terminating and potentially a denial of service. En la gema yajl-ruby 1.3.0 para Ruby, cuando se envía un archivo JSON manipulado a Yajl::Parser.new.parse, todo el proceso de ruby sufre un cierre inesperado con un SIGABRT en la función yajl_string_decode en yajl_encode.c. Esto tiene como resultado que todo el proceso de ruby finalice y posiblemente se provoque una denegación de servicio. • https://github.com/brianmario/yajl-ruby/issues/176 https://lists.debian.org/debian-lts-announce/2017/11/msg00010.html https://lists.debian.org/debian-lts-announce/2023/07/msg00013.html https://lists.debian.org/debian-lts-announce/2023/08/msg00003.html https://rubygems.org/gems/yajl-ruby • CWE-134: Use of Externally-Controlled Format String •
CVSS: 7.5EPSS: 1%CPEs: 24EXPL: 0CVE-2017-14033 – ruby: Buffer underrun in OpenSSL ASN1 decode
https://notcve.org/view.php?id=CVE-2017-14033
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. El método decode en el módulo OpenSSL::ASN1 en Ruby en versiones anteriores a la 2.2.8, versiones 2.3.x anteriores a 2.3.5, y 2.4.x hasta la 2.4.1 permite que los atacantes provoquen una denegación de servicio (cierre inesperado del intérprete) mediante una string manipulada. It was found that the decode method of the OpenSSL::ASN1 module was vulnerable to buffer underrun. An attacker could pass a specially crafted string to the application in order to crash the ruby interpreter, causing a denial of service. • http://www.securityfocus.com/bid/100868 http://www.securitytracker.com/id/1039363 http://www.securitytracker.com/id/1042004 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://lists.debian.org/debian-lts-announce/2018/07/msg00012.html https://security.gentoo.org/glsa/201710-18 https://www.debian.org/security/2017/dsa-4031 https://www.ruby-lang.org/en/news/2017/09/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 9.3EPSS: 0%CPEs: 14EXPL: 0CVE-2017-10784 – ruby: Escape sequence injection vulnerability in the Basic authentication of WEBrick
https://notcve.org/view.php?id=CVE-2017-10784
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. El código de autenticación Basic en la biblioteca WEBrick en Ruby en versiones anteriores a la 2.2.8, 2.3.x anteriores a la 2.3.5 y 2.4.x hasta la 2.4.1 permite que atacantes remotos inyecten secuencias de escape del emulador del terminal en su registro y que puedan ejecutar comandos arbitrarios mediante un nombre de usuario manipulado. It was found that WEBrick did not sanitize all its log messages. If logs were printed in a terminal, an attacker could interact with the terminal via the use of escape sequences. • http://www.securityfocus.com/bid/100853 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://lists.debian.org/debian-lts-announce/2018/07/msg00012.html https://security.gentoo.org/glsa/201710-18 https://usn.ubuntu.com/3528-1 https://usn&# • CWE-117: Improper Output Neutralization for Logs CWE-287: Improper Authentication •

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 •
