The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2009:0473 :
Updated kernel packages that fix several security issues and several
bugs are now available for Red Hat Enterprise Linux 5.
This update has been rated as having important security impact by the
Red Hat Security Response Team.
The kernel packages contain the Linux kernel, the core of any Linux
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
* network interfaces using the IBM eHEA Ethernet device driver could
not be successfully configured under low-memory conditions.
* bonding with the 'arp_validate=3' option may have prevented fail
* 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.
* the ixgbe driver double counted the number of received bytes and
* the Wacom Intuos3 Lens Cursor device did not work correctly with the
Wacom Intuos3 12x12 tablet. (BZ#489460)
* on the Itanium(r) architecture, nanosleep() caused commands which
used it, such as sleep and usleep, to sleep for one second more than
* 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(r)
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.
* it was possible for posix_locks_deadlock() to enter an infinite loop
(under the BKL), causing a system hang. (BZ#496842)
Users should upgrade to these updated packages, which contain
backported patches to correct these issues. The system must be
rebooted for this update to take effect.
