Subject: New Linux kernel 2.4.27 packages fix several issues
--------------------------------------------------------------------------
Debian Security Advisory DSA XXX-1 security@debian.org
http://www.debian.org/security/ Dann Frazier
XXXXX 8th, 2005 http://www.debian.org/security/faq
--------------------------------------------------------------------------
Package : kernel-source-2.4.27
Vulnerability : several
Problem-Type : local/remote
Debian-specific: no
CVE ID : CVE-2005-4798 CVE-2006-2935 CVE-2006-1528 CVE-2006-2444
CVE-2006-2446 CVE-2006-3745 CVE-2006-4535 CVE-2006-4145
Several local and remote vulnerabilities have been discovered in the Linux
kernel that may lead to a denial of service or the execution of arbitrary
code. The Common Vulnerabilities and Exposures project identifies the
following problems:
CVE-2005-4798
Assar discovered a buffer overlow in the NFS readlink handling code
that would allows a malicious remote server to cause a denail of
service (crash) using a long symlink.
CVE-2006-2935
Diego Calleja Garcia discovered a potential buffer overflow in the
dvd_read_bca() function that could allow aribrary code execution via
a malicious CDROM device
CVE-2006-1528
Douglas Gilbert reported a bug in the sg driver that allows local
users to oops the kernel by performing dio transfers from the sg
driver to memory mapped IO space.
CVE-2006-2444
Patrick McHardy reported a memory corruption bug in snmp_trap_decode that
could be used by remote attackers to crash a system.
CVE-2006-2446
A race between the kfree_skb and __skb_unlink functions allows remote
users to crash a system.
CVE-2006-3745
Wei Wang discovered a vulnerability in the SCTP subsystem that can be
exploited for local privilege escalation.
CVE-2006-4145
Colin discovered a bug in the UDF filesystem that allows local users to
hang a system when truncating files.
CVE-2006-4535
David Miller reported a problem with the fix for CVE-2006-3745 that allows
local users to crash the system using via an SCTP socket with a certain
SO_LINGER value.
The following matrix explains which kernel version for which architecture
fix the problems mentioned above:
Debian 3.1 (sarge)
Source 2.4.27-10sarge4
Alpha architecture 2.4.27-10sarge4
ARM architecture 2.4.27-2sarge4
Intel IA-32 architecture 2.4.27-10sarge4
Intel IA-64 architecture 2.4.27-10sarge4
Motorola 680x0 architecture 2.4.27-3sarge4
Big endian MIPS 2.4.27-10.sarge4.040815-1
Little endian MIPS 2.4.27-10.sarge4.040815-1
PowerPC architecture 2.4.27-10sarge4
IBM S/390 architecture 2.4.27-2sarge4
Sun Sparc architecture 2.4.27-9sarge4
The following matrix lists additional packages that were rebuilt for
compatibility with or to take advantage of this update:
Debian 3.1 (sarge)
fai-kernels 1.9.1sarge4
kernel-image-2.4.27-speakup 2.4.27-1.1sarge3
mindi-kernel 2.4.27-2sarge3
systemimager 3.2.3-6sarge3
We recommend that you upgrade your kernel package immediately and reboot
the machine. If you have built a custom kernel from the kernel source
package, you will need to rebuild to take advantage of these fixes.
Upgrade Instructions
--------------------
wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.
If you are using the apt-get package manager, use the line for
sources.list as given below:
apt-get update
will update the internal database
apt-get upgrade
will install corrected packages
You may use an automated update by adding the resources from the
footer to the proper configuration.
Debian GNU/Linux 3.1 alias sarge
--------------------------------
These files will probably be moved into the stable distribution on
its next update.
