NVD Description

Note: Versions mentioned in the description apply only to the upstream 389-ds-base-snmp package and not the 389-ds-base-snmp package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

Marked is a markdown parser and compiler. Prior to version 4.0.10, the regular expression block.def may cause catastrophic backtracking against some strings and lead to a regular expression denial of service (ReDoS). Anyone who runs untrusted markdown through a vulnerable version of marked and does not use a worker with a time limit may be affected. This issue is patched in version 4.0.10. As a workaround, avoid running untrusted markdown through marked or run marked on a worker thread and set a reasonable time limit to prevent draining resources.
