NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby193-rubygem-mail package and not the ruby193-rubygem-mail package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

The mail gem before 2.5.5 for Ruby (aka A Really Ruby Mail Library) is vulnerable to SMTP command injection via CRLF sequences in a RCPT TO or MAIL FROM command, as demonstrated by CRLF sequences immediately before and after a DATA substring.
