NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby3.4-rails-8.0 package and not the ruby3.4-rails-8.0 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

Active Support is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, Active Support number helpers accept strings containing scientific notation (e.g. 1e10000), which BigDecimal expands into extremely large decimal representations. This can cause excessive memory allocation and CPU consumption when the expanded number is formatted, possibly resulting in a DoS vulnerability. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.
