The remote Red Hat host is missing one or more security updates.
Updated kernel packages that fix various security issues and a bug 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
These updated packages fix the following security issues :
* A security flaw was found in the Linux kernel memory copy routines,
when running on certain AMD64 systems. If an unsuccessful attempt to
copy kernel memory from source to destination memory locations
occurred, the copy routines did not zero the content at the
destination memory location. This could allow a local unprivileged
user to view potentially sensitive data. (CVE-2008-2729, Important)
* 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.
* Brandon Edwards discovered a missing length validation check in the
Linux kernel DCCP module reconciliation feature. This could allow a
local unprivileged user to cause a heap overflow, gaining privileges
for arbitrary code execution. (CVE-2008-2358, Moderate)
As well, these updated packages fix the following bug :
* Due to a regression, 'gettimeofday' may have gone backwards on
certain x86 hardware. This issue was quite dangerous for
time-sensitive systems, such as those used for transaction systems and
databases, and may have caused applications to produce incorrect
results, or even crash.
Red Hat Enterprise Linux 5 users are advised to upgrade to these
updated packages, which contain backported patches to resolve these
