SynopsisThe remote host is missing a security update.
DescriptionUpdated kernel packages are now available as part of ongoing support
and maintenance of Red Hat Enterprise Linux version 2.1. This is the
seventh regular update.
This security advisory has been rated as having important security
impact by the Red Hat Security Response Team.
The Linux kernel handles the basic functions of the operating system.
This is the seventh regular kernel update to Red Hat Enterprise Linux
The following security updates were made :
A flaw in fragment queuing was discovered that affected the Linux 2.4
and Linux 2.6 kernel netfilter subsystem. On systems configured to
filter or process network packets (for example those configured to do
firewalling), a remote attacker could send a carefully crafted set of
fragmented packets to a machine and cause a denial of service (system
crash). In order to sucessfully exploit this flaw, the attacker would
need to know (or guess) some aspects of the firewall ruleset in place
on the target system to be able to craft the right fragmented packets.
A flaw was discovered in the Linux PPP driver. On systems allowing
remote users to connect to a server using ppp, a remote client could
cause a denial of service (system crash). (CVE-2005-0384)
A flaw was discovered in the bluetooth driver system. On system where
the bluetooth modules are loaded, a local user could use this flaw to
gain elevated (root) privileges. (CVE-2005-0750)
An integer overflow flaw was discovered in the ubsec_keysetup function
in the Broadcom 5820 cryptonet driver. On systems using this driver, a
local user could cause a denial of service (crash) or possibly gain
elevated privileges. (CVE-2004-0619) Please note that this update
contains an unpatched kernel module called bcm5820_old for backwards
compatibility which is still vulnerable to CVE-2004-0619.
The following device drivers have been updated to new versions :
mptfusion: 2.05.16 -> 2.05.16.02 bcm5820: 1.17 -> 1.81 cciss: 2.4.52
-> 2.4.54 qla2x00: 6.04.01 -> 7.01.01
There were many bug fixes in various parts of the kernel. The ongoing
effort to resolve these problems has resulted in a marked improvement
in the reliability and scalability of Red Hat Enterprise Linux 2.1.
Bug fixes include: - Fixes an incorrect and ever-changing physical_id
field in /proc/cpuinfo. - Now recognizes a particular e1000 device
(PCI ID 8086:1014) - Fixes a panic in disk quota code - Fixes a bug in
which msync(...MS_SYNC) returns before the data is written to disk -
Adds new devices to the SCSI scan list so they can be initialized and
handled properly: LSI ProFibre 4000R, HP HSV200/210, HP MSA, STK
OPENstorage D178. - Fixes a potential format overflow in
/proc/partitions - Restores module parameters to the e100 driver for
compatibility with existing customer scripts. - Fixes a bug in which
cat'ing /proc/mdstat while adding/removing devices can cause a kernel
All Red Hat Enterprise Linux 2.1 users are advised to upgrade their
kernels to the packages associated with their machine architectures
and configurations as listed in this erratum.
Please note that a vulnerability addressed by this update
(CVE-2005-0449) required a change to the kernel module ABI which could
cause third party modules to not work. However, Red Hat is currently
not aware of any module that would be affected by this change.
SolutionUpdate the affected package(s).
