Subject: MDKSA-2003:066-1 - Updated kernel packages fix multiple vulnerabilities
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
________________________________________________________________________
Mandrake Linux Security Update Advisory
________________________________________________________________________
Package name: kernel
Advisory ID: MDKSA-2003:066-1
Date: July 21st, 2003
Original Advisory 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.
For full instructions on how to properly upgrade your kernel, please
review http://www.mandrakesecure.net/en/docs/magic.php.
Update:
These new packages fix some bugs with compiling kernels using xconfig
and also fix problems with XFS ACLs not being present in the kernel.
Problems with ipsec have also been corrected. A problem with gdb not
working on systems where XFS was used for the root filesystem has also
been corrected. They also address CAN-2003-0476: A file read race
existed in the execve() system call.
9.1/PPC kernels are now also available.
