There is no fixed version for Ubuntu:20.04 cmark-gfm.

NVD Description

Note: Versions mentioned in the description apply only to the upstream cmark-gfm package and not the cmark-gfm package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

cmark-gfm is GitHub's fork of cmark, a CommonMark parsing and rendering library and program in C. In versions prior 0.29.0.gfm.7, a crafted markdown document can trigger an out-of-bounds read in the validate_protocol function. We believe this bug is harmless in practice, because the out-of-bounds read accesses malloc metadata without causing any visible damage.This vulnerability has been patched in 0.29.0.gfm.7.
