Debian DSA-4586-1 : ruby2.5 - security update

high Nessus Plugin ID 132108
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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 could result in unauthorized access by bypassing intended path matchings, denial of service, or the execution of arbitrary code.

Solution

Upgrade the ruby2.5 packages.

For the stable distribution (buster), these problems have been fixed in version 2.5.5-3+deb10u1.
