| Description: | Summary:
The remote host is missing an update for the 'kernel'
package(s) announced via the referenced advisory.
Vulnerability Insight:
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
Security fixes:
* A flaw in sctp_packet_config() in the Linux kernel's Stream Control
Transmission Protocol (SCTP) implementation could allow a remote attacker
to cause a denial of service. (CVE-2010-3432, Important)
* A missing integer overflow check in snd_ctl_new() in the Linux kernel's
sound subsystem could allow a local, unprivileged user on a 32-bit system
to cause a denial of service or escalate their privileges. (CVE-2010-3442,
Important)
Red Hat would like to thank Dan Rosenberg for reporting CVE-2010-3442.
Bug fixes:
* Forward time drift was observed on virtual machines using PM
timer-based kernel tick accounting and running on KVM or the Microsoft
Hyper-V Server hypervisor. Virtual machines that were booted with the
divider=x kernel parameter set to a value greater than 1 and that showed
the following in the kernel boot messages were subject to this issue:
time.c: Using PM based timekeeping
Fine grained accounting for the PM timer is introduced which eliminates
this issue. However, this fix uncovered a bug in the Xen hypervisor,
possibly causing backward time drift. If this erratum is installed in Xen
HVM guests that meet the aforementioned conditions, it is recommended that
the host use kernel-xen-2.6.18-194.26.1.el5 or newer, which includes a fix
(BZ#641915) for the backward time drift. (BZ#629237)
* With multipath enabled, systems would occasionally halt when the
do_cciss_request function was used. This was caused by wrongly-generated
requests. Additional checks have been added to avoid the aforementioned
issue. (BZ#640193)
* A Sun X4200 system equipped with a QLogic HBA spontaneously rebooted and
logged a Hyper-Transport Sync Flood Error to the system event log. A
Maximum Memory Read Byte Count restriction was added to fix this bug.
(BZ#640919)
* For an active/backup bonding network interface with VLANs on top of it,
when a link failed over, it took a minute for the multicast domain to be
rejoined. This was caused by the driver not sending any IGMP join packets.
The driver now sends IGMP join packets and the multicast domain is rejoined
immediately. (BZ#641002)
* Replacing a disk and trying to rebuild it afterwards caused the system to
panic. When a domain validation request for a hot plugged drive was sent,
the mptscsi driver did not validate its existence. This could result in the
driver accessing random memory and causing the crash. A check has been
added that describes the new ...
