  "description": "cmark-gfm is GitHub\u0027s 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 \u0060validate_protocol\u0060 function. We believe this bug is harmless in practice, because the out-of-bounds read accesses \u0060malloc\u0060 metadata without causing any visible damage.This vulnerability has been patched in 0.29.0.gfm.7.",
