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.
