Description

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

 - ERB is a templating system for Ruby. Ruby 2.7.0 (before ERB 2.2.0 was published on rubygems.org)
 introduced an `@_init` instance variable guard in `ERB#result` and `ERB#run` to prevent code execution
 when an ERB object is reconstructed via `Marshal.load` (deserialization). However, three other public
 methods that also evaluate `@src` via `eval()` were not given the same guard: `ERB#def_method`,
 `ERB#def_module`, and `ERB#def_class`. An attacker who can trigger `Marshal.load` on untrusted data in a
 Ruby application that has `erb` loaded can use `ERB#def_module` (zero-arg, default parameters) as a code
 execution sink, bypassing the `@_init` protection entirely. ERB 4.0.3.1, 4.0.4.1, 6.0.1.1, and 6.0.4 patch
 the issue. (CVE-2026-41316)

Solution

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