Descriptions
drivers/gpu/drm/i915/i915_gem.c in the Graphics Execution Manager (GEM) in the Intel i915 driver in the Direct Rendering Manager (DRM) subsystem in the Linux kernel before 2.6.36 does not properly validate pointers to blocks of memory, which allows local users to write to arbitrary kernel memory locations, and consequently gain privileges, via crafted use of the ioctl interface, related to (1) pwrite and (2) pread operations.
drivers/gpu/drm/i915/i915_gem.c en el Graphics Execution Manager (GEM) en el controlador Intel i915 en el subsistema Direct Rendering Manager (DRM) en el kernel de Linux anterior a v2.6.36 no valida correctamente los punteros a los bloques de la memoria, lo cual permite a usuarios locales escribir en ubicaciones de memoria del núcleo a su elección, y por consiguiente obtener privilegios, mediante el uso de la interfaz ioctl manipulada, relacionado con (1) pwrite y (2) operaciones pread.
USN-1074-1 fixed vulnerabilities in linux-fsl-imx51 in Ubuntu 9.10. This update provides the corresponding updates for Ubuntu 10.04. Multiple vulnerabilities have been discovered and addressed in the Linux kernel. Al Viro discovered a race condition in the TTY driver. Dan Rosenberg discovered that the MOVE_EXT ext4 ioctl did not correctly check file permissions. Neil Brown discovered that NFSv4 did not correctly check certain write requests. David Howells discovered that DNS resolution in CIFS could be spoofed. Various other issues have also been addressed.
