- Summary
- cmark-gfm out-of-bounds read in validate_protocol
- Details

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_protocolfunction. We believe this bug is harmless in practice, because the out-of-bounds read accessesmallocmetadata without causing any visible damage.This vulnerability has been patched in 0.29.0.gfm.7. - Database specific
