Trustix Secure Linux 2

Race condition in the page fault handler (fault.c) for Linux kernel 2.2.x to 2.2.7, 2.4 to 2.4.29, and 2.6 to 2.6.10, when running on multiprocessor machines, allows local users to execute arbitrary code via concurrent threads that share the same virtual memory space and simultaneously request stack expansion.

Unknown vulnerability in the PPP driver for the Linux kernel 2.6.8.1 allows remote attackers to cause a denial of service (kernel crash) via a pppd client.

Unknown vulnerability in Linux kernel 2.x may allow local users to modify the group ID of files, such as NFS exported files in kernel 2.4.

Floating point information leak in the context switch code for Linux 2.4.x only checks the MFH bit but does not verify the FPH owner, which allows local users to read register values of other processes by setting the MFH bit.
