RubyGems version 2.6.12 and earlier is vulnerable to maliciously crafted gem specifications that include terminal escape characters. Printing the gem specification would execute terminal escape sequences. RubyGems 2.6.12 y anteriores es vulnerable a especificaciones de gemas manipuladas maliciosamente que incluyen caracteres de escapada de terminal. Imprimir la especificación de las gemas ejecutaría secuencias de escapada de terminal.

https://notcve.org/view.php?id=CVE-2017-0902
RubyGems version 2.6.12 and earlier is vulnerable to a DNS hijacking vulnerability that allows a MITM attacker to force the RubyGems client to download and install gems from a server that the attacker controls. RubyGems 2.6.12 y anteriores es vulnerable a secuestro de DNS, lo que permite a un atacante Man-in-the-Middle (MitM) forzar el cliente RubyGems a que descargue e instale gemas desde un servidor que está bajo el control del atacante. A vulnerability was found where rubygems did not sanitize DNS responses when requesting the hostname of the rubygems server for a domain, via a _rubygems._tcp DNS SRV query. An attacker with the ability to manipulate DNS responses could direct the gem command towards a different domain. • http://blog.rubygems.org/2017/08/27/2.6.13-released.html http://www.securityfocus.com/bid/100586 http://www.securitytracker.com/id/1039249 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/rubygems/rubygems/commit/8d91516fb7037ecfb27622f605dc40245e0f8d32 https://hackerone.com/reports/218088 https://lists.debian.org/debian- • CWE-138: Improper Neutralization of Special Elements CWE-346: Origin Validation Error CWE-350: Reliance on Reverse DNS Resolution for a Security-Critical Action •
