Descriptions
The DNS resolution functionality in the CIFS implementation in the Linux kernel before 2.6.35, when CONFIG_CIFS_DFS_UPCALL is enabled, relies on a user's keyring for the dns_resolver upcall in the cifs.upcall userspace helper, which allows local users to spoof the results of DNS queries and perform arbitrary CIFS mounts via vectors involving an add_key call, related to a "cache stuffing" issue and MS-DFS referrals.
La funcionalidad de resolución DNS en el kernel de Linux anterior a v2.6.35, cuando CONFIG_CIFS_DFS_UPCALL está activado, cuenta con el "keyring" de usuario para la "upcall" dns_resolver en el espacio de usuario cifs.upcall, lo que permite a usuarios locales secuestrar los resultados de las consultas DNS y realizar montajes (mounts) CIFS de su elección a través de vectores que involucran una llamada add_key, relacionado con un cuestión de relleno de caché (stuffing) y referencias MS-DFS.
