The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2010:0146 :
Updated kernel packages that fix multiple security issues and several
bugs are now available for Red Hat Enterprise Linux 4.
The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.
The kernel packages contain the Linux kernel, the core of any Linux
This update fixes the following security issues :
* a NULL pointer dereference flaw was found in the sctp_rcv_ootb()
function in the Linux kernel Stream Control Transmission Protocol
(SCTP) implementation. A remote attacker could send a specially
crafted SCTP packet to a target system, resulting in a denial of
service. (CVE-2010-0008, Important)
* a NULL pointer dereference flaw was found in the Linux kernel.
During a core dump, the kernel did not check if the Virtual
Dynamically-linked Shared Object page was accessible. On Intel 64 and
AMD64 systems, a local, unprivileged user could use this flaw to cause
a kernel panic by running a crafted 32-bit application.
* an information leak was found in the print_fatal_signal()
implementation in the Linux kernel. When
'/proc/sys/kernel/print-fatal-signals' is set to 1 (the default value
is 0), memory that is reachable by the kernel could be leaked to
user-space. This issue could also result in a system crash. Note that
this flaw only affected the i386 architecture. (CVE-2010-0003,
* on AMD64 systems, it was discovered that the kernel did not ensure
the ELF interpreter was available before making a call to the
SET_PERSONALITY macro. A local attacker could use this flaw to cause a
denial of service by running a 32-bit application that attempts to
execute a 64-bit application. (CVE-2010-0307, Moderate)
* missing capability checks were found in the ebtables implementation,
used for creating an Ethernet bridge firewall. This could allow a
local, unprivileged user to bypass intended capability restrictions
and modify ebtables rules. (CVE-2010-0007, Low)
This update also fixes the following bugs :
* under some circumstances, a locking bug could have caused an online
ext3 file system resize to deadlock, which may have, in turn, caused
the file system or the entire system to become unresponsive. In either
case, a reboot was required after the deadlock. With this update,
using resize2fs to perform an online resize of an ext3 file system
works as expected. (BZ#553135)
* some ATA and SCSI devices were not honoring the barrier=1 mount
option, which could result in data loss after a crash or power loss.
This update applies a patch to the Linux SCSI driver to ensure ordered
write caching. This solution does not provide cache flushes
it does provide data integrity on devices that have no write caching
(or where write caching is disabled) and no command queuing. For
systems that have command queuing or write cache enabled there is no
guarantee of data integrity after a crash. (BZ#560563)
* it was found that lpfc_find_target() could loop continuously when
scanning a list of nodes due to a missing spinlock. This missing
spinlock allowed the list to be changed after the list_empty() test,
resulting in a NULL value, causing the loop. This update adds the
spinlock, resolving the issue. (BZ#561453)
* the fix for CVE-2009-4538 provided by RHSA-2010:0020 introduced a
regression, preventing Wake on LAN (WoL) working for network devices
using the Intel PRO/1000 Linux driver, e1000e. Attempting to configure
WoL for such devices resulted in the following error, even when
configuring valid options :
'Cannot set new wake-on-lan settings: Operation not supported not
This update resolves this regression, and WoL now works as expected
for network devices using the e1000e driver. (BZ#565496)
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.
