Synopsis: Important: kernel security and bug fix update
Issue date: 2010-12-01
CVE Names: CVE-2010-3432 CVE-2010-3442
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)
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 newly-added device and reloads
the iocPg3 data from the firmware if needed. (BZ#641137)
* An attempt to create a VLAN interface on a bond of two bnx2 adapters
in two switch configurations resulted in a soft lockup after a few
seconds. This was caused by an incorrect use of a bonding pointer. With
this update, soft lockups no longer occur and creating a VLAN interface
works as expected. (BZ#641254)
* Erroneous pointer checks could have caused a kernel panic. This was
due to a critical value not being copied when a network buffer was
duplicated and consumed by multiple portions of the kernel's network
stack. Fixing the copy operation resolved this bug. (BZ#642746)
* A typo in a variable name caused it to be dereferenced in either
mkdir() or create() which could cause a kernel panic. (BZ#643342)
* SCSI high level drivers can submit SCSI commands which would never be
completed when the device was offline. This was caused by a missing
callback for the request to complete the given command. SCSI requests
are now terminated by calling their callback when a device is offline.
(BZ#644816)
* A kernel panic could have occurred on systems due to a recursive lock
in the 3c59x driver. Recursion is now avoided and this kernel panic no
longer occurs. (BZ#648407)
The system must be rebooted for this update to take effect.
