Descriptions

The glob implementation in tnftpd (formerly lukemftpd), as used in Apple OS X before 10.11, allows remote attackers to cause a denial of service (memory consumption and daemon outage) via a STAT command containing a crafted pattern, as demonstrated by multiple instances of the {..,..,..}/* substring.

La implementación de glob en tnftpd (anteriormente lukemftpd), tal como se utiliza en Apple OS X en versiones anteriores a 10.11 permite a atacantes remotos provocar una denegación de servicio (corrupción de memoria e interrupción de demonio) a través de un comando STAT que contiene un patrón manipulado, según lo demostrado por múltiples casos de la subcadena {..,..,..}/*.

OS X El Capitan 10.11 is now available and addresses close to 100 vulnerabilities that may exist in prior releases.
