  operating system.

  This update addresses the following security issues:
  
  * 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)
  
  * 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)
  
  * missing capability checks were found in the SBNI WAN driver which could
  allow a local user to bypass intended capability restrictions.
  (CVE-2008-3525, Important)
  
  * the do_truncate() and generic_file_splice_write() functions did not clear
  the setuid and setgid bits. This could allow a local, unprivileged user to
  obtain access to privileged information. (CVE-2008-4210, Important)
  
  * a buffer overflow flaw was found in Integrated Services Digital Network
  (ISDN) subsystem. A local, unprivileged user could use this flaw to cause a
  denial of service. (CVE-2007-6063, Moderate)
  
  * multiple NULL pointer dereferences were found in various Linux kernel
  network drivers. These drivers were missing checks for terminal validity,
  which could allow privilege escalation. (CVE-2008-2812, Moderate)
  
  * a deficiency was found in the Linux kernel virtual filesystem (VFS)
  implementation. This could allow a local, unprivileged user to attempt file
  creation within deleted directories, possibly causing a denial of service.
  (CVE-2008-3275, Moderate)
  
  This update also fixes the following bugs:
  
  * the incorrect kunmap function was used in nfs_xdr_readlinkres. kunmap()
  was used where kunmap_atomic() should have been. As a consequence, if an
  NFSv2 or NFSv3 server exported a volume containing a symlink which included
  a path equal to or longer than the local system's PATH_MAX, accessing the
  link caused a kernel oops. This has been corrected in this update.
  
  * mptctl_gettargetinfo did not check if pIoc3 was NULL before using it as a
  pointer. This caused a kernel panic in mptctl_gettargetinfo in some
  circumstances. A check has been added which prevents this.
  
  * lost tick compensation code in the timer interrupt routine triggered
  without apparent cause. When running as a fully-virtuali ...
