New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

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.
