NVD Description
Note: Versions mentioned in the description apply only to the upstream perl package and not the perl package as distributed by Alpine.
See How to fix? for Alpine:3.9 relevant fixed versions and status.
Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular expression quantifiers have an integer overflow.
