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. For the stable distribution (stretch), these problems have been fixed in version 2.3.3-1+deb9u3. We recommend that you upgrade your ruby2.3 packages.
