"value": "cmark-gfm is GitHub's extended version of the C reference implementation of CommonMark. Prior to versions 0.29.0.gfm.3 and 0.28.3.gfm.21, an integer overflow in cmark-gfm's table row parsing `table.c:row_from_string` may lead to heap memory corruption when parsing tables who's marker rows contain more than UINT16_MAX columns. The impact of this heap corruption ranges from Information Leak to Arbitrary Code Execution depending on how and where `cmark-gfm` is used. If `cmark-gfm` is used for rendering remote user controlled markdown, this vulnerability may lead to Remote Code Execution (RCE) in applications employing affected versions of the `cmark-gfm` library. This vulnerability has been patched in the following cmark-gfm versions 0.29.0.gfm.3 and 0.28.3.gfm.21. A workaround is available. The vulnerability exists in the table markdown extensions of cmark-gfm. Disabling the table extension will prevent this vulnerability from being triggered."

"value": "cmark-gfm es la versi\u00f3n extendida de GitHub de la implementaci\u00f3n de referencia en C de CommonMark. En versiones anteriores a 0.29.0.gfm.3 y 0.28.3.gfm.21, un desbordamiento de enteros en el an\u00e1lisis de filas de tablas de cmark-gfm, \"table.c:row_from_string\", pod\u00eda conllevar a una corrupci\u00f3n de la memoria de la pila cuando eran analizadas tablas cuyas filas de marcadores conten\u00edan m\u00e1s de UINT16_MAX columnas. El impacto de esta corrupci\u00f3n de memoria va desde un filtrado de informaci\u00f3n hasta una ejecuci\u00f3n de c\u00f3digo arbitrario, dependiendo de c\u00f3mo y d\u00f3nde es usado \"cmark-gfm\". Si \"cmark-gfm\" es usado para renderizar markdown controlado por usuarios remotos, esta vulnerabilidad puede conllevar a una Ejecuci\u00f3n de C\u00f3digo Remota (RCE) en aplicaciones que empleen versiones afectadas de la biblioteca \"cmark-gfm\". Esta vulnerabilidad ha sido parcheada en las siguientes versiones de cmark-gfm: 0.29.0.gfm.3 y 0.28.3.gfm.21. Se presenta una medida de mitigaci\u00f3n disponible. La vulnerabilidad se presenta en las extensiones de tablas markdown de cmark-gfm. Si es deshabilitada la extensi\u00f3n de la tabla, podr\u00e1 evitarse que sea producida esta vulnerabilidad"
