"value": "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."

En versiones anteriores a la 0.29.0.gfm.7, un documento de rebajas manipulado puede desencadenar una lectura fuera de los l\u00edmites en la funci\u00f3n `validate_protocol` . Creemos que este error es inofensivo en la pr\u00e1ctica, porque la lectura fuera de los l\u00edmites accede a los metadatos \"malloc\" sin causar ning\u00fan da\u00f1o visible. Esta vulnerabilidad ha sido parcheada en 0.29.0.gfm.7."
