Synopsis:	Important: kernel security and bug fix update
Issue date:	2009-05-07
CVE Names:	CVE-2008-4307 CVE-2009-0787 CVE-2009-0834
                 CVE-2009-1336 CVE-2009-1337

This update fixes the following security issues:

* a logic error was found in the do_setlk() function of the Linux kernel
Network File System (NFS) implementation. If a signal interrupted a lock
request, the local POSIX lock was incorrectly created. This could cause 
a denial of service on the NFS server if a file descriptor was closed 
before its corresponding lock request returned. (CVE-2008-4307, Important)

* a deficiency was found in the Linux kernel system call auditing
implementation on 64-bit systems. This could allow a local, unprivileged
user to circumvent a system call audit configuration, if that 
configuration filtered based on the "syscall" number or arguments.
(CVE-2009-0834, Important)

* the exit_notify() function in the Linux kernel did not properly reset 
the exit signal if a process executed a set user ID (setuid) application 
before exiting. This could allow a local, unprivileged user to elevate 
their privileges. (CVE-2009-1337, Important)

* a flaw was found in the ecryptfs_write_metadata_to_contents() function 
of the Linux kernel eCryptfs implementation. On systems with a 4096 byte
page-size, this flaw may have caused 4096 bytes of uninitialized kernel
memory to be written into the eCryptfs file headers, leading to an
information leak. Note: Encrypted files created on systems running the
vulnerable version of eCryptfs may contain leaked data in the eCryptfs 
file headers. This update does not remove any leaked data. Refer to the
Knowledgebase article in the References section for further information.
(CVE-2009-0787, Moderate)

* the Linux kernel implementation of the Network File System (NFS) did 
not properly initialize the file name limit in the nfs_server data 
structure. This flaw could possibly lead to a denial of service on a 
client mounting an NFS share. (CVE-2009-1336, Moderate)

This update also fixes the following bugs:

* the enic driver (Cisco 10G Ethernet) did not operate under 
virtualization. (BZ#472474)

* network interfaces using the IBM eHEA Ethernet device driver could not 
be successfully configured under low-memory conditions. (BZ#487035)

* bonding with the "arp_validate=3" option may have prevented fail 
overs. (BZ#488064)

* when running under virtualization, the acpi-cpufreq module wrote 
"Domain attempted WRMSR" errors to the dmesg log. (BZ#488928)

* NFS clients may have experienced deadlocks during unmount. (BZ#488929)

* the ixgbe driver double counted the number of received bytes and 
packets. (BZ#489459)

* the Wacom Intuos3 Lens Cursor device did not work correctly with the
Wacom Intuos3 12x12 tablet. (BZ#489460)

* on the Itanium® architecture, nanosleep() caused commands which used 
it, such as sleep and usleep, to sleep for one second more than 
expected. (BZ#490434)

* a panic and corruption of slab cache data structures occurred on 
64-bit PowerPC systems when clvmd was running. (BZ#491677)

* the NONSTOP_TSC feature did not perform correctly on the Intel®
microarchitecture (Nehalem) when running in 32-bit mode. (BZ#493356)

* keyboards may not have functioned on IBM eServer System p machines 
after a certain point during installation or afterward. (BZ#494293)

* using Device Mapper Multipathing with the qla2xxx driver resulted in
frequent path failures. (BZ#495635)

* if the hypervisor was booted with the dom0_max_vcpus parameter set to
less than the actual number of CPUs in the system, and the cpuspeed 
service was started, the hypervisor could crash. (BZ#495931)

* using Openswan to provide an IPsec virtual private network eventually
resulted in a CPU soft lockup and a system crash. (BZ#496044)

* it was possible for posix_locks_deadlock() to enter an infinite loop
(under the BKL), causing a system hang. (BZ#496842)

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