A flaw has been identified in glibc. In an uncommon situation, the gaih_inet function may use memory that has been freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge.

Este problema solo se puede explotar cuando se llama a la función getaddrinfo y la base de datos de hosts en /etc/nsswitch.conf está configurada con SUCCESS=continue o SUCCESS=merge.
