            Mandrake Linux Security Update Advisory

Package name: kernel Advisory ID: MDKSA-2003:066 Date: June 11th, 2003

Affected versions: 9.1


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.

As well, a number of bug fixes were made in the 9.1 kernel including:

  • Support for more machines that did not work with APIC
  • Audigy2 support
  • New/updated modules: prims25, adiusbadsl, thinkpad, ieee1394, orinoco, via-rhine,
  • Fixed SiS IOAPIC
  • IRQ balancing has been fixed for SMP
  • Updates to ext3
  • The previous ptrace fix has been redone to work better

MandrakeSoft encourages all users to upgrade to these new kernels. Updated kernels will be available shortly for other supported platforms and architectures.
