Mandrake Linux Security Update Advisory

Problem Description:

Multiple vulnerabilities were discovered and fixed in the Linux
kernel.

• CAN-2003-0001: Multiple ethernet network card drivers do not
  pad frames with null bytes which allows remote attackers to obtain
  information from previous packets or kernel memory by using special
  malformed packets.
• CAN-2003-0244: The route cache implementation in the 2.4 kernel
  and the Netfilter IP conntrack module allows remote attackers to
  cause a Denial of Service (DoS) via CPU consumption due to packets
  with forged source addresses that cause a large number of hash
  table collisions related to the PREROUTING chain.
• CAN-2003-0246: The ioperm implementation in 2.4.20 and earlier
  kernels does not properly restrict privileges, which allows local
  users to gain read or write access to certain I/O ports.
• CAN-2003-0247: A vulnerability in the TTY layer of the 2.4
  kernel allows attackers to cause a kernel oops resulting in a
  DoS.
• CAN-2003-0248: The mxcsr code in the 2.4 kernel allows
  attackers to modify CPU state registers via a malformed
  address.
• CAN-2003-0462: A file read race existed in the execve() system
  call.

Kernels for 9.1/x86 are also available (see MDKSA-2003:066).

MandrakeSoft encourages all users to upgrade to these new
kernels.

For full instructions on how to properly upgrade your kernel,
please review http://www.mandrakesecure.net/en/docs/magic.php.
