Red Hat Security Advisory Synopsis: Important: kernel security and bug fix update Advisory ID: RHSA-2008:0508-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2008-0508.html Issue date: 2008-06-25 CVE Names: CVE-2008-0598 CVE-2008-1367 CVE-2008-2365 CVE-2008-2729 =====================================================================
  1. Summary:

Updated kernel packages that fix several security issues and a bug 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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, noarch, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, noarch, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, noarch, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, noarch, 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)
  • Alexey Dobriyan discovered a race condition in the Linux kernel process-tracing system call, ptrace. A local unprivileged user could use this flaw to cause a denial of service (kernel hang). (CVE-2008-2365, 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)
  • It was discovered that the Linux kernel handled string operations in the opposite way to the GNU Compiler Collection (GCC). This could allow a local unprivileged user to cause memory corruption. (CVE-2008-1367, Low)

As well, these updated packages fix the following bug:

  • On systems with a large number of CPUs (more than 16), multiple applications calling the "times()" system call may have caused a system hang.

Red Hat Enterprise Linux 4 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 http://kbase.redhat.com/faq/FAQ_58_10188

5. Bugs fixed (http://bugzilla.redhat.com/): 433938 - CVE-2008-0598 kernel: linux x86_64 ia32 emulation leaks uninitialized data 437312 - CVE-2008-1367 Kernel doesn't clear DF for signal handlers 449101 - [4.7] System goes unresponsive if times() syscall is called concurrently on many cpus 449359 - CVE-2008-2365 kernel: ptrace: Crash on PTRACE_{ATTACH,DETACH} race 451271 - CVE-2008-2729 kernel: [x86_64] The string instruction version didn't zero the output on exception.
