"value": "A use-after-free vulnerability introduced in glibc upstream version 2.14 was found in the way the tilde expansion was carried out. Directory paths containing an initial tilde followed by a valid username were affected by this issue. A local attacker could exploit this flaw by creating a specially crafted path that, when processed by the glob function, would potentially lead to arbitrary code execution. This was fixed in version 2.32."

"value": "Una vulnerabilidad de uso de la memoria previamente liberada introducida en glibc versiones anteriores a la versi\u00f3n 2.14, se descubri\u00f3 en la manera en que se llev\u00f3 a cabo la expansi\u00f3n de tilde. Las rutas de directorios que conten\u00edan una tilde inicial seguida de un nombre de usuario v\u00e1lido estaban afectadas por este problema. Un atacante local podr\u00eda explotar este fallo creando una ruta especialmente dise\u00f1ada que, al ser procesada por la funci\u00f3n glob, podr\u00eda conllevar a una ejecuci\u00f3n de c\u00f3digo arbitraria. Esto fue corregido en la versi\u00f3n 2.32."
