The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2009:0264 :
Updated kernel packages that resolve several security issues 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 addresses the following security issues :
* a memory leak in keyctl handling. A local user could use this flaw
to deplete kernel memory, eventually leading to a denial of service.
* a buffer overflow in the Linux kernel Partial Reliable Stream
Control Transmission Protocol (PR-SCTP) implementation. This could,
potentially, lead to a denial of service if a Forward-TSN chunk is
received with a large stream ID. (CVE-2009-0065, Important)
* a flaw when handling heavy network traffic on an SMP system with
many cores. An attacker who could send a large amount of network
traffic could create a denial of service. (CVE-2008-5713, Important)
* the code for the HFS and HFS Plus (HFS+) file systems failed to
properly handle corrupted data structures. This could, potentially,
lead to a local denial of service. (CVE-2008-4933, CVE-2008-5025, Low)
* a flaw was found in the HFS Plus (HFS+) file system implementation.
This could, potentially, lead to a local denial of service when write
operations are performed. (CVE-2008-4934, Low)
In addition, these updated packages fix the following bugs :
* when using the nfsd daemon in a clustered setup, kernel panics
appeared seemingly at random. These panics were caused by a race
condition in the device-mapper mirror target.
* the clock_gettime(CLOCK_THREAD_CPUTIME_ID, ) syscall returned a
smaller timespec value than the result of previous clock_gettime()
function execution, which resulted in a negative, and nonsensical,
elapsed time value.
* nfs_create_rpc_client was called with a 'flavor' parameter which was
usually ignored and ended up unconditionally creating the RPC client
with an AUTH_UNIX flavor. This caused problems on AUTH_GSS mounts when
the credentials needed to be refreshed. The credops did not match the
authorization type, which resulted in the credops dereferencing an
incorrect part of the AUTH_UNIX rpc_auth struct.
* when copy_user_c terminated prematurely due to reading beyond the
end of the user buffer and the kernel jumped to the exception table
entry, the rsi register was not cleared. This resulted in exiting back
to user code with garbage in the rsi register.
* the hexdump data in s390dbf traces was incomplete. The length of the
data traced was incorrect and the SAN payload was read from a
different place then it was written to.
* when using connected mode (CM) in IPoIB on ehca2 hardware, it was
not possible to transmit any data.
* when an application called fork() and pthread_create() many times
and, at some point, a thread forked a child and then attempted to call
the setpgid() function, then this function failed and returned and
ESRCH error value.
Users should upgrade to these updated packages, which contain
backported patches to correct these issues. Note: for this update to
take effect, the system must be rebooted.
