CVE-2023-22485

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.

Summary		(es) cmmark-gfm es la bifurcación de GitHub de cmark, una librería y programa de análisis y representación de CommonMark en C. En versiones anteriores a la 0.29.0.gfm.7, un documento de rebajas manipulado puede desencadenar una lectura fuera de los límites en la función `validate_protocol` . Creemos que este error es inofensivo en la práctica, porque la lectura fuera de los límites accede a los metadatos "malloc" sin causar ningún daño visible. Esta vulnerabilidad ha sido parcheada en 0.29.0.gfm.7.
