CVE-2017-0899

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.

A vulnerability was found where rubygems did not properly sanitize gems' specification text. A specially crafted gem could interact with the terminal via the use of escape sequences.

Ruby is an extensible, interpreted, object-oriented, scripting language. It has features to process text files and to perform system management tasks. Security Fix: It was discovered that the Net::FTP module did not properly process filenames in combination with certain operations. A remote attacker could exploit this flaw to execute arbitrary commands by setting up a malicious FTP server and tricking a user or Ruby application into downloading files with specially crafted names using the Net::FTP module.
