The remote host is missing updates announced in
advisory RHSA-2008:0089.
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
These new kernel packages fix the following security issues:
A flaw was found in the virtual filesystem (VFS). An unprivileged local
user could truncate directories to which they had write permission
this
could render the contents of the directory inaccessible. (CVE-2008-0001,
Important)
A flaw was found in the Xen PAL emulation on Intel 64 platforms. A guest
Hardware-assisted virtual machine (HVM) could read the arbitrary physical
memory of the host system, which could make information available to
unauthorized users. (CVE-2007-6416, Important)
A flaw was found in the way core dump files were created. If a local user
can get a root-owned process to dump a core file into a directory, which
the user has write access to, they could gain read access to that core
file, potentially containing sensitive information. (CVE-2007-6206, Moderate)
A buffer overflow flaw was found in the CIFS virtual file system. A
remote,authenticated user could issue a request that could lead to a denial
of service. (CVE-2007-5904, Moderate)
A flaw was found in the sysfs_readdir function. A local user could create
a race condition which would cause a denial of service (kernel oops).
(CVE-2007-3104, Moderate)
As well, these updated packages fix the following bugs:
* running the strace -f command caused strace to hang, without displaying
information about child processes.
* unmounting an unresponsive, interruptable NFS mount, for example, one
mounted with the intr option, may have caused a system crash.
* a bug in the s2io.ko driver prevented VLAN devices from being added.
Attempting to add a device to a VLAN, for example, running the vconfig
add [device-name] [vlan-id] command caused vconfig to fail.
* tux used an incorrect open flag bit. This caused problems when building
packages in a chroot environment, such as mock, which is used by the koji
build system.
Red Hat Enterprise Linux 5 users are advised to upgrade to these updated
packages, which contain backported patches to resolve these issues.
