The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2015:0164 :
Updated kernel packages that fix one security issue and several bugs
are now available for Red Hat Enterprise Linux 5.
Red Hat Product Security has rated this update as having Moderate
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link in the References section.
The kernel packages contain the Linux kernel, the core of any Linux
* A flaw was found in the way the Linux kernel's splice() system call
validated its parameters. On certain file systems, a local,
unprivileged user could use this flaw to write past the maximum file
size, and thus crash the system. (CVE-2014-7822, Moderate)
Red Hat would like to thank Akira Fujita of NEC for reporting this
This update also fixes the following bugs :
* Previously, hot-unplugging of a virtio-blk device could in some
cases lead to a kernel panic, for example during in-flight I/O
requests. This update fixes race condition in the hot-unplug code in
the virtio_blk.ko module. As a result, hot unplugging of the
virtio-blk device no longer causes the guest kernel oops when there
are in-flight I/O requests. (BZ#1006536)
* Before this update, due to a bug in the error-handling path, a
corrupted metadata block could be used as a valid block. With this
update, the error handling path has been fixed and more checks have
been added to verify the metadata block. Now, when a corrupted
metadata block is encountered, it is properly marked as corrupted and
handled accordingly. (BZ#1034403)
* Previously, an incorrectly initialized variable resulted in a random
value being stored in the variable that holds the number of default
ACLs, and is sent in the SET_PATH_INFO data structure. Consequently,
the setfacl command could, under certain circumstances, fail with an
'Invalid argument' error. With this update, the variable is correctly
initialized to zero, thus fixing the bug. (BZ#1105625)
All kernel users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. The system
must be rebooted for this update to take effect.
