Debian DSA-4259-1 : ruby2.3 - security update
High Nessus Plugin ID 111468
SynopsisThe remote Debian host is missing a security-related update.
DescriptionSeveral 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.
SolutionUpgrade the ruby2.3 packages.
For the stable distribution (stretch), these problems have been fixed in version 2.3.3-1+deb9u3.
