Multiple integer overflows in Alchemy LCD frame-buffer drivers in the Linux kernel before 3.12 allow local users to create a read-write memory mapping for the entirety of kernel memory, and consequently gain privileges, via crafted mmap operations, related to the (1) au1100fb_fb_mmap function in drivers/video/au1100fb.c and the (2) au1200fb_fb_mmap function in drivers/video/au1200fb.c. Múltiples desbordamientos de enteros en drivers frame-buffer en Alchemy LCD del kernel de Linux anterior a la versión 3.12 permite a usuarios locales crear y leer-escribir asignación de memoria para la totalidad de memoria del kernel, y consecuentemente obtener privilegios a través de operaciones manipuladas mmap, relacionadas con (1) au1100fb_fb_mmap function en drivers/video/au1100fb.c y (2) au1200fb_fb_mmap function en drivers/video/au1200fb.c. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=7314e613d5ff9f0934f7a0f74ed7973b903315d1 http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00003.html http://lists.opensuse.org/opensuse-updates/2014-02/msg00045.html http://www.openwall.com/lists/oss-security/2013/11/04/22 http://www.ubuntu.com/usn/USN-2036-1 http://www.ubuntu.com/usn/USN-2037-1 http://www.ub • CWE-189: Numeric Errors •

The uio_mmap_physical function in drivers/uio/uio.c in the Linux kernel before 3.12 does not validate the size of a memory block, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via crafted mmap operations, a different vulnerability than CVE-2013-4511. La función uio_mmap_physical en drivers/uio/uio.c del kernel de Linux anterior a la versión 3.12 no valida el tamaño de un bloque de memoria, lo que permite a usuarios locales provocar una denegación de servicio (corrupción de memoria) o posiblemente obtener privilegios a través de operaciones mmap manipuladas, una vulnerabilidad diferente a CVE-2013-4511. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=7314e613d5ff9f0934f7a0f74ed7973b903315d1 http://www.openwall.com/lists/oss-security/2013/11/04/22 http://www.ubuntu.com/usn/USN-2064-1 http://www.ubuntu.com/usn/USN-2065-1 http://www.ubuntu.com/usn/USN-2066-1 http://www.ubuntu.com/usn/USN-2067-1 http://www.ubuntu.com/usn/USN-2068-1 http://www.ubuntu.com/usn/USN-2069-1 http://www.ubuntu.com/usn/USN-2070-1 http: • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
