The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2008:0973 :
Updated kernel packages that resolve several security issues and fix
various bugs are now available for Red Hat Enterprise Linux 3.
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 :
* Tavis Ormandy discovered a deficiency in the Linux kernel 32-bit and
64-bit emulation. This could allow a local, unprivileged user to
prepare and run a specially-crafted binary which would use this
deficiency to leak uninitialized and potentially sensitive data.
* a possible kernel memory leak was found in the Linux kernel Simple
Internet Transition (SIT) INET6 implementation. This could allow a
local, unprivileged user to cause a denial of service. (CVE-2008-2136,
* missing capability checks were found in the SBNI WAN driver which
could allow a local user to bypass intended capability restrictions.
* the do_truncate() and generic_file_splice_write() functions did not
clear the setuid and setgid bits. This could allow a local,
unprivileged user to obtain access to privileged information.
* a buffer overflow flaw was found in Integrated Services Digital
Network (ISDN) subsystem. A local, unprivileged user could use this
flaw to cause a denial of service. (CVE-2007-6063, Moderate)
* multiple NULL pointer dereferences were found in various Linux
kernel network drivers. These drivers were missing checks for terminal
validity, which could allow privilege escalation. (CVE-2008-2812,
* a deficiency was found in the Linux kernel virtual filesystem (VFS)
implementation. This could allow a local, unprivileged user to attempt
file creation within deleted directories, possibly causing a denial of
service. (CVE-2008-3275, Moderate)
This update also fixes the following bugs :
* the incorrect kunmap function was used in nfs_xdr_readlinkres.
kunmap() was used where kunmap_atomic() should have been. As a
consequence, if an NFSv2 or NFSv3 server exported a volume containing
a symlink which included a path equal to or longer than the local
system's PATH_MAX, accessing the link caused a kernel oops. This has
been corrected in this update.
* mptctl_gettargetinfo did not check if pIoc3 was NULL before using it
as a pointer. This caused a kernel panic in mptctl_gettargetinfo in
some circumstances. A check has been added which prevents this.
* lost tick compensation code in the timer interrupt routine triggered
without apparent cause. When running as a fully-virtualized client,
this spurious triggering caused the 64-bit version of Red Hat
Enterprise Linux 3 to present highly inaccurate times. With this
update the lost tick compensation code is turned off when the
operating system is running as a fully-virtualized client under Xen or
All Red Hat Enterprise Linux 3 users should install this updated
kernel which addresses these vulnerabilities and fixes these bugs.
