Descriptions
kernel/trace/ftrace.c in the Linux kernel before 2.6.35.5, when debugfs is enabled, does not properly handle interaction between mutex possession and llseek operations, which allows local users to cause a denial of service (NULL pointer dereference and outage of all function tracing files) via an lseek call on a file descriptor associated with the set_ftrace_filter file.
kernel/trace/ftrace.c en el kernel Linux anterior a la versión 2.6.36-rc5, cuando está habilitado debugfs, no maneja adecuadamente la interacción entre la posesión mutex y operaciones llseek, lo que permite a usuarios locales provocar una denegación de servicio (interrupción de todas las funciones de rastreo de archivos) mediante una llamada lseek en un descriptor de fichero asociado con el fichero set_ftrace_filter.
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.
