Hi,
The following vulnerabilities were published for cmark-gfm.
CVE-2023-22483[0]:
| cmark-gfm is GitHub's fork of cmark, a CommonMark parsing and
| rendering library and program in C. Versions prior to 0.29.0.gfm.7 are
| subject to several polynomial time complexity issues in cmark-gfm that
| may lead to unbounded resource exhaustion and subsequent denial of
| service. Various commands, when piped to cmark-gfm with large values,
| cause the running time to increase quadratically. These
| vulnerabilities have been patched in version 0.29.0.gfm.7.

CVE-2023-22484[1]:
| cmark-gfm is GitHub's fork of cmark, a CommonMark parsing and
| rendering library and program in C. Versions prior to 0.29.0.gfm.7 are
| subject to a polynomial time complexity issue in cmark-gfm that may
| lead to unbounded resource exhaustion and subsequent denial of
| service. This vulnerability has been patched in 0.29.0.gfm.7.

CVE-2023-22485[2]:
| 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.

CVE-2023-22486[3]:
| cmark-gfm is GitHub's fork of cmark, a CommonMark parsing and
| rendering library and program in C. Versions prior to 0.29.0.gfm.7
| contain a polynomial time complexity issue in handle_close_bracket
| that may lead to unbounded resource exhaustion and subsequent denial
| of service. This vulnerability has been patched in 0.29.0.gfm.7.
