CVE-2011-1759

Desbordamiento de entero en la función sys_oabi_semtimedop en arch/arm/kernel/sys_oabi-compat.c en el Kernel de Linux anterior a v2.6.39 en la plataforma ARM, cuando CONFIG_OABI_COMPAT es habilitada, permite a usuarios locales obtener privilegios o causar una denegación de servicio (daños en la pila de memoria) mediante la utilización de un argumento manipulado y una condición condición de carrera.

Aristide Fattori and Roberto Paleari reported a flaw in the Linux kernel's handling of IPv4 icmp packets. A remote user could exploit this to cause a denial of service. Vegard Nossum discovered a leak in the kernel's inotify_init() system call. A local, unprivileged user could exploit this to cause a denial of service. An error was discovered in the kernel's handling of CUSE (Character device in Userspace). A local attacker might exploit this flaw to escalate privilege, if access to /dev/cuse has been modified to allow non-root users. Various other issues were also addressed.
