"value": "Apport creates a world writable lock file with root ownership in the world writable /var/lock/apport directory. If the apport/ directory does not exist (this is not uncommon as /var/lock is a tmpfs), it will create the directory, otherwise it will simply continue execution using the existing directory. This allows for a symlink attack if an attacker were to create a symlink at /var/lock/apport, changing apport's lock file location. This file could then be used to escalate privileges, for example. Fixed in versions 2.20.1-0ubuntu2.23, 2.20.9-0ubuntu7.14, 2.20.11-0ubuntu8.8 and 2.20.11-0ubuntu22."

Si el directorio apport/ no existe (esto no es raro ya que /var/lock es un tmpfs), crear\u00e1 el directorio, de lo contrario, simplemente continuar\u00e1 la ejecuci\u00f3n usando el directorio existente. Esto permite un ataque de tipo symlink si un atacante creara un enlace simb\u00f3lico en el directorio /var/lock/apport, cambiando la ubicaci\u00f3n del archivo de bloqueo de apport. Este archivo podr\u00eda ser utilizado para escalar privilegios, por ejemplo. Corregido en las versiones 2.20.1-0ubuntu2.23, 2.20.9-0ubuntu7.14, 2.20.11-0ubuntu8.8 y 2.20.11-0ubuntu22."
