The table extension in GitHub Flavored Markdown before version 0.29.0.gfm.1
takes O(n * n) time to parse certain inputs. An attacker could craft a
markdown table which would take an unreasonably long time to process,
causing a denial of service. This issue does not affect the upstream cmark
project. The issue has been fixed in version 0.29.0.gfm.1.
