CVE-2014-5471

Vulnerabilidad de consumo de pila en la función parse_rock_ridge_inode_internal en fs/isofs/rock.c en el kernel de Linux hasta 3.16.1 permite a usuarios locales causar una denegación de servicio (recursividad sin control y caída o reinicio del sistema) a través de un imagen iso9660 manipulado con una entrada CL que se refiere a una entrada del directorio que tiene una entrada CL.

It was found that the parse_rock_ridge_inode_internal() function of the Linux kernel's ISOFS implementation did not correctly check relocated directories when processing Rock Ridge child link (CL) tags. An attacker with physical access to the system could use a specially crafted ISO image to crash the system or, potentially, escalate their privileges on the system.

A flaw was found in the way the Linux kernel handled GS segment register base switching when recovering from a #SS fault on an erroneous return to user space. A local, unprivileged user could use this flaw to escalate their privileges on the system. A flaw was found in the way the Linux kernel's SCTP implementation handled malformed or duplicate Address Configuration Change Chunks. A remote attacker could use either of these flaws to crash the system. A flaw was found in the way the Linux kernel's SCTP implementation handled the association's output queue. A remote attacker could send specially crafted packets that would cause the system to use an excessive amount of memory, leading to a denial of service.
