 Problem Description:

 Multiple vulnerabilities in the Linux kernel have been discovered and
 fixed in this update.  The following have been fixed in the 2.4
 kernels:
 
 Colin Percival discovered a vulnerability in Intel's Hyper-Threading
 technology could allow a local user to use a malicious thread to create
 covert channels, monitor the execution of other threads, and obtain
 sensitive information such as cryptographic keys via a timing attack on
 memory cache misses.  This has been corrected by disabling HT support
 in all kernels (CAN-2005-0109).
 
 When forwarding fragmented packets, a hardware assisted checksum could
 only be used once which could lead to a Denial of Service attack or
 crash by remote users (CAN-2005-0209).
 
 A flaw in the Linux PPP driver was found where on systems allowing
 remote users to connect to a server via PPP, a remote client could
 cause a crash, resulting in a Denial of Service (CAN-2005-0384).
 
 An information leak in the ext2 filesystem code was found where when a
 new directory is created, the ext2 block written to disk is not
 initialized (CAN-2005-0400).
 
 A signedness error in the copy_from_read_buf function in n_tty.c
 allows local users to read kernel memory via a negative argument
 (CAN-2005-0530).
 
 George Guninski discovered a buffer overflow in the ATM driver
 where the atm_get_addr() function does not validate its arguments
 sufficiently which could allow a local attacker to overwrite large
 portions of kernel memory by supplying a negative length argument. This
 could potentially lead to the execution of arbitrary code
 (CAN-2005-0531).
 
 A flaw when freeing a pointer in load_elf_library was found that could
 be abused by a local user to potentially crash the machine causing a
 Denial of Service (CAN-2005-0749).
 
 A problem with the Bluetooth kernel stack in kernels 2.4.6 through
 2.4.30-rc1 and 2.6 through 2.6.11.5  could be used by a local attacker
 to gain root access or crash the machine (CAN-2005-0750).
 
 A race condition in the Radeon DRI driver allows a local user with DRI
 privileges to execute arbitrary code as root (CAN-2005-0767).
 
 Paul Starzetz found an integer overflow in the ELF binary format
 loader's code dump function in kernels prior to and including 2.4.31-pre1
 and 2.6.12-rc4.  By creating and executing a specially
 crafted ELF executable, a local attacker could exploit this to
 execute arbitrary code with root and kernel privileges
 (CAN-2005-1263).
