Debian DSA-4259-1 : ruby2.3 - security update

critical Nessus Plugin ID 111468

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Several vulnerabilities have been discovered in the interpreter for the Ruby language, which may result in incorrect processing of HTTP/FTP, directory traversal, command injection, unintended socket creation or information disclosure.

This update also fixes several issues in RubyGems which could allow an attacker to use specially crafted gem files to mount cross-site scripting attacks, cause denial of service through an infinite loop, write arbitrary files, or run malicious code.

Solution

Upgrade the ruby2.3 packages.

For the stable distribution (stretch), these problems have been fixed in version 2.3.3-1+deb9u3.
