Regex search

Posted by hsbt on 23 Apr 2024

We have released the Ruby version 3.0.7, 3.1.5, 3.2.4 and 3.3.1
that have a security fix for an arbitrary memory address read
vulnerability in Regex search. This vulnerability has been
assigned the CVE identifier CVE-2024-27282.


Details

An issue was discovered in Ruby 3.x through 3.3.0.

If attacker-supplied data is provided to the Ruby regex compiler,
it is possible to extract arbitrary heap data relative to the start
of the text, including pointers and sensitive strings.


Recommended action

We recommend to update the Ruby to version 3.3.1 or later. In order
to ensure compatibility with older Ruby series, you may update as
follows instead:

     For Ruby 3.0 users: Update to 3.0.7
     For Ruby 3.1 users: Update to 3.1.5
     For Ruby 3.2 users: Update to 3.2.4


Affected versions

     Ruby 3.0.6 or lower
