Echo: ruby-3.2: security update to 3.2.11+e3ruby-3.3: security update to 3.3.11+e3

low Tenable Self-Hosted Container Security Plugin ID 460558

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Net::IMAP implements Internet Message Access Protocol (IMAP) client functionality in Ruby. Prior to 0.6.5
 and 0.5.15, several Net::IMAP commands accept a raw string argument which is only validated to prevent
 CRLF injection and then sent verbatim. If this string is derived from user-controlled input, an attacker
 can force the next command to be absorbed as a continuation of the first command. This will cause the
 first command to eventually fail, but also prevents it from returning until another command is sent (from
 another thread). That other command will not return until the connection is closed. This vulnerability is
 fixed in 0.6.5 and 0.5.15. (CVE-2026-47241)

Solution

Update the ruby-3.2 library and its related packages to version 3.2.11+e3 or later.
