The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2009:1522 :
Updated kernel packages that fix multiple security issues and several
bugs are now available for Red Hat Enterprise Linux 4.
This update has been rated as having moderate 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 :
* 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,
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.
* the driver version number in the ata_piix driver was not changed
between Red Hat Enterprise Linux 4.7 and Red Hat Enterprise 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
* 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.
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.
