Novell Client 4.91 SP4 nwfs.sys Local Privilege Escalation

This module exploits a flaw in the nwfs.sys driver to overwrite data in kernel space. The corruption occurs while handling ioctl requests with code 0x1438BB, where a 0x00000009 dword is written to an arbitrary address. An entry within the HalDispatchTable is overwritten in order to execute...

kernel: futex: Handle user space corruption gracefully

The wakefutexpi function in kernel/futex.c in the Linux kernel before 2.6.33-rc7 does not properly handle certain unlock operations for a Priority Inheritance PI futex, which allows local users to cause a denial of service OOPS and possibly have unspecified other impact via vectors involving...
