# CVE-2024-47889: rails: Action Mailer is a framework for designing email service layers CVE-2024-47889 is fixed in 14 products on 1 platform, first by rails 2:4.2.10-0ubuntu4+esm1, released October 16, 2024. It is not reported as exploited. Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2024-47889 - Priority: Routine - CVSS: n/a (Medium) - EPSS: 0.0094 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Oct 16, 2024 ## Description Action Mailer is a framework for designing email service layers. Starting in version 3.0.0 and prior to versions 6.1.7.9, 7.0.8.5, 7.1.4.1, and 7.2.1.1, there is a possible ReDoS vulnerability in the block_format helper in Action Mailer. Carefully crafted text can cause the block_format helper to take an unexpected amount of time, possibly resulting in a DoS vulnerability. All users running an affected release should either upgrade to versions 6.1.7.9, 7.0.8.5, 7.1.4.1, or 7.2.1.1 or apply the relevant patch immediately. As a workaround, users can avoid calling the `block_format` helper or upgrade to Ruby 3.2. Ruby 3.2 has mitigations for this problem, so Rails applications using Ruby 3.2 or newer are unaffected. Rails 8.0.0.beta1 requires Ruby 3.2 or greater so is unaffected. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | rails Debian 12.15 (bookworm) |
