Oracle Linux 4 : kernel (ELSA-2008-0607)

Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2008:0607 :

Updated kernel packages that fix a security issue and several bugs are
now available for Red Hat Enterprise Linux 4.

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
operating system.

These updated packages fix the following security issue :

* 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,
Important)

As well, these updated packages fix the following bugs :

* a possible kernel hang on hugemem systems, due to a bug in NFS,
which may have caused systems to become unresponsive, has been
resolved.

* an inappropriate exit condition occurred in the
architecture-specific 'mmap()' realization, which fell into an
infinite loop under certain conditions. On 64-bit systems, this issue
may have manifested itself to users as a soft lockup, or process
hangs.

* due to a bug in hardware initialization in the 'ohci_hcd' kernel
module, the kernel may have failed with a NULL pointer dereference. On
64-bit PowerPC systems, this may have caused booting to fail, and drop
to xmon. On other platforms, a kernel oops occurred.

* due to insufficient locks in task termination code, a panic may have
occurred in the 'sys_times()' system call on SMP machines.

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