CVE-2013-2596

Una determinada version de Android v4.1.2 en dispositivos Motorola Razr HD, Razr M, y Atrix HD con el chipset Qualcomm MSM8960 permite a atacantes físicamente próximos obtener acceso de root entrando en el modo de depuración USB, usando Android Debug Bridge (ADB) para establecer una conexión USB, y cargar y ejecutar el programa pwn Motochopper.

An integer overflow flaw was found in the way the Linux kernel's Frame Buffer device implementation mapped kernel memory to user space via the mmap syscall. A local user able to access a frame buffer device file (/dev/fb*) could possibly use this flaw to escalate their privileges on the system.

The kernel packages contain the Linux kernel, the core of any Linux operating system. An integer overflow flaw was found in the way the Linux kernel's Frame Buffer device implementation mapped kernel memory to user space via the mmap syscall. A local user able to access a frame buffer device file could possibly use this flaw to escalate their privileges on the system. It was found that the Xen hypervisor x86 CPU emulator implementation did not correctly handle certain instructions with segment overrides, potentially resulting in a memory corruption. A malicious guest user could use this flaw to read arbitrary data relating to other guests, cause a denial of service on the host, or potentially escalate their privileges on the host.

Linux kernel fb_mmap function in drivers/video/fbmem.c contains an integer overflow vulnerability that allows for privilege escalation.
