Red Hat Security Advisory

 

Synopsis: Important: kernel security and bug fix update

Advisory ID: RHSA-2008:0519-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2008-0519.html

Issue date: 2008-06-25

CVE Names: CVE-2008-0598 CVE-2008-2358 CVE-2008-2729

=====================================================================

 

1. Summary:

 

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.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, noarch, x86_64

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, noarch, ppc, s390x, x86_64

 

3. Description:

 

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.

 

4. Solution:

 

Before applying this update, make sure that all previously-released

errata relevant to your system have been applied.

 

This update is available via Red Hat Network. Details on how to use

the Red Hat Network to apply this update are available at

5. Bugs fixed (http://bugzilla.redhat.com/):

 

433938 - CVE-2008-0598 kernel: linux x86_64 ia32 emulation leaks uninitialized data

447389 - CVE-2008-2358 kernel: dccp: sanity check feature length

451271 - CVE-2008-2729 kernel: [x86_64] The string instruction version didn't zero the output on exception.
