Synopsis:	Moderate: kernel security and bug fix update
Issue date:	2010-10-19
CVE Names:	CVE-2010-2942 CVE-2010-3067 CVE-2010-3477

This update fixes the following security issues:

* Information leak flaws were found in the Linux kernel Traffic Control
Unit implementation. A local attacker could use these flaws to cause the
kernel to leak kernel memory to user-space, possibly leading to the
disclosure of sensitive information. (CVE-2010-2942, Moderate)

* A flaw was found in the tcf_act_police_dump() function in the Linux
kernel network traffic policing implementation. A data structure in
tcf_act_police_dump() was not initialized properly before being copied
to user-space. A local, unprivileged user could use this flaw to cause
an information leak. (CVE-2010-3477, Moderate)

* A missing upper bound integer check was found in the sys_io_submit()
function in the Linux kernel asynchronous I/O implementation. A local,
unprivileged user could use this flaw to cause an information leak.
(CVE-2010-3067, Low)

This update also fixes the following bugs:

* When two systems using bonding devices in the adaptive load balancing
(ALB) mode communicated with each other, an endless loop of ARP replies
started between these two systems due to a faulty MAC address update.
With this update, the MAC address update no longer creates unneeded ARP
replies. (BZ#629239)

* When running the Connectathon NFS Testsuite with certain clients and
Scientific Linux 4.8 as the server, nfsvers4, lock, and test2 failed
the Connectathon test. (BZ#625535)

* For UDP/UNIX domain sockets, due to insufficient memory barriers in
the network code, a process sleeping in select() may have missed
notifications about new data. In rare cases, this bug may have caused a
process to sleep forever. (BZ#640117)

* In certain situations, a bug found in either the HTB or TBF network
packet schedulers in the Linux kernel could have caused a kernel panic
when using Broadcom network cards with the bnx2 driver. (BZ#624363)

* Previously, allocating fallback cqr for DASD reserve/release IOCTLs
failed because it used the memory pool of the respective device. This
update preallocates sufficient memory for a single reserve/release
request. (BZ#626828)

* In some situations a bug prevented "force online" succeeding for a
DASD device. (BZ#626827)

* Using the "fsstress" utility may have caused a kernel panic. (BZ#633968)

* This update introduces additional stack guard patches. (BZ#632515)

* A bug was found in the way the megaraid_sas driver handled physical
disks and management IOCTLs. All physical disks were exported to the
disk layer, allowing an oops in megasas_complete_cmd_dpc() when
completing the IOCTL command if a timeout occurred. (BZ#631903)

* Previously, a warning message was returned when a large amount of
messages was passed through netconsole and a considerable amount of
network load was added. With this update, the warning message is no
longer displayed. (BZ#637729)

* Executing a large "dd" command (1 to 5GB) on an iSCSI device with the
qla3xxx driver caused a system crash due to the incorrect storing of a
private data structure. With this update, the size of the stored data
structure is checked and the system crashes no longer occur. (BZ#624364)

The system must be rebooted for this update to take effect.
