The remote host is missing updates announced in
advisory RHSA-2008:0519.
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
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. (CVE-2008-0598, Important)
* 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 issues.
