NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-195-1.NASL description The object oriented scripting language Ruby supports safely executing untrusted code with two mechanisms: safe level and taint flag on objects. Dr. Yutaka Oiwa discovered a vulnerability that allows Ruby methods to bypass these mechanisms. In systems which use this feature, this could be exploited to execute Ruby code beyond the restrictions specified in each safe level. Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues. last seen 2020-06-01 modified 2020-06-02 plugin id 20609 published 2006-01-15 reporter Ubuntu Security Notice (C) 2005-2019 Canonical, Inc. / NASL script (C) 2006-2016 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/20609 title Ubuntu 4.10 / 5.04 : ruby1.8 vulnerability (USN-195-1) NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2005-799.NASL description Updated ruby packages that fix an arbitrary command execution issue are now available. This update has been rated as having moderate security impact by the Red Hat Security Response Team. [Updated 25 Oct 2005] Errata has been updated to include missing packages for Red Hat Enterprise Linux 3. Ruby is an interpreted scripting language for object-oriented programming. A bug was found in the way ruby handles eval statements. It is possible for a malicious script to call eval in such a way that can allow the bypass of certain safe-level restrictions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-2337 to this issue. Users of Ruby should update to these erratum packages, which contain a backported patch and are not vulnerable to this issue. last seen 2020-06-01 modified 2020-06-02 plugin id 20049 published 2005-10-19 reporter This script is Copyright (C) 2005-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/20049 title RHEL 2.1 / 3 / 4 : ruby (RHSA-2005:799) NASL family Debian Local Security Checks NASL id DEBIAN_DSA-864.NASL description Yutaka Oiwa discovered a bug in Ruby, the interpreter for the object-oriented scripting language, that can cause illegal program code to bypass the safe level and taint flag protections check and be executed.
