CentOS 9 : ruby-3.0.4-160.el9

critical Nessus Plugin ID 191346

Language:

Synopsis

The remote CentOS host is missing one or more security updates for ruby.

Description

The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ruby-3.0.4-160.el9 build changelog.

 - A double free was found in the Regexp compiler in Ruby 3.x before 3.0.4 and 3.1.x before 3.1.2. If a victim attempts to create a Regexp from untrusted user input, an attacker may be able to write to unexpected memory locations. (CVE-2022-28738)

 - There is a buffer over-read in Ruby before 2.6.10, 2.7.x before 2.7.6, 3.x before 3.0.4, and 3.1.x before 3.1.2. It occurs in String-to-Float conversion, including Kernel#Float and String#to_f. (CVE-2022-28739)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the CentOS 9 Stream ruby package.
