Synopsis:	Moderate: kernel security and bug fix update
Issue date:	2009-10-22
CVE Names:	CVE-2005-4881 CVE-2009-3228

CVE-2005-4881 kernel: netlink: fix numerous padding memleaks
CVE-2009-3228 kernel: tc: uninitialised kernel memory leak

This update fixes the following security issues:

* multiple, missing initialization flaws were found in the Linux kernel.
Padding data in several core network structures was not initialized
properly before being sent to user-space. These flaws could lead to
information leaks. (CVE-2005-4881, CVE-2009-3228, Moderate)

This update also fixes the following bugs:

* a packet duplication issue was fixed via the RHSA-2008:0665 update;
however, the fix introduced a problem for systems using network bonding:
Backup slaves were unable to receive ARP packets. When using network
bonding in the "active-backup" mode and with the "arp_validate=3" 
option, the bonding driver considered such backup slaves as being down 
(since they were not receiving ARP packets), preventing successful 
failover to these devices. (BZ#519384)

* 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#519386)

* the driver version number in the ata_piix driver was not changed 
between Scientific Linux 4.7 and Scientific Linux 4.8, even though
changes had been made between these releases. This could have prevented 
the driver from loading on systems that check driver versions, as this 
driver appeared older than it was. (BZ#519389)

* a bug in nlm_lookup_host() could have led to un-reclaimed locks on 
file systems, resulting in the umount command failing. This bug could 
have also prevented NFS services from being relocated correctly in 
clustered environments. (BZ#519656)

* the data buffer ethtool_get_strings() allocated, for the igb driver, 
was smaller than the amount of data that was copied in 
igb_get_strings(), because of a miscalculation in IGB_QUEUE_STATS_LEN, 
resulting in memory corruption. This bug could have led to a kernel 
panic. (BZ#522738)

* in some situations, write operations to a TTY device were blocked even
when the O_NONBLOCK flag was used. A reported case of this issue 
occurred when a single TTY device was opened by two users (one using 
blocking mode, and the other using non-blocking mode). (BZ#523930)

* a deadlock was found in the cciss driver. In rare cases, this caused 
an NMI lockup during boot. Messages such as "cciss: controller cciss[x]
failed, stopping." and "cciss[x]: controller not responding." may have
been displayed on the console. (BZ#525725)

* on 64-bit PowerPC systems, a rollover bug in the ibmveth driver could
have caused a kernel panic. In a reported case, this panic occurred on a
system with a large uptime and under heavy network load. (BZ#527225)

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