NVD Description
Note: Versions mentioned in the description apply only to the upstream ceph package and not the ceph package as distributed by RHEL.
In mistune through 2.0.2, support of inline markup is implemented by using regular expressions that can involve a high amount of backtracking on certain edge cases. This behavior is commonly named catastrophic backtracking.
