Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2008:0167

The remote host is missing updates announced in
advisory RHSA-2008:0167.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

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)

As well, these updated packages fix the following bugs:

* a bug was found in the Linux kernel audit subsystem. When the audit
daemon was setup to log the execve system call with a large number
of arguments, the kernel could run out out memory while attempting to
create audit log messages. This could cause a kernel panic. In these
updated packages, large audit messages are split into acceptable sizes,
which resolves this issue.

* on certain Intel chipsets, it was not possible to load the acpiphp
module using the modprobe acpiphp command. Because the acpiphp module
did not recurse across PCI bridges, hardware detection for PCI hot plug
slots failed. In these updated packages, hardware detection works

* on IBM System z architectures that run the IBM z/VM hypervisor, the IBM
eServer zSeries HiperSockets network interface (layer 3) allowed ARP
packets to be sent and received, even when the NOARP flag was set. These
ARP packets caused problems for virtual machines.

* it was possible for the iounmap function to sleep while holding a lock.
This may have caused a deadlock for drivers and other code that uses the
iounmap function. In these updated packages, the lock is dropped before
the sleep code is called, which resolves this issue.

Red Hat Enterprise Linux 4 users are advised to upgrade to these updated
packages, which contain backported patches to resolve these issues.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
