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.
