  This update fixes the following security issues:

  * the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a
  setuid or setgid program was executed. A local, unprivileged user could use
  this flaw to bypass the mmap_min_addr protection mechanism and perform a
  NULL pointer dereference attack, or bypass the Address Space Layout
  Randomization (ASLR) security feature. (CVE-2009-1895, Important)

  * it was discovered that, when executing a new process, the clear_child_tid
  pointer in the Linux kernel is not cleared. If this pointer points to a
  writable portion of the memory of the new program, the kernel could corrupt
  four bytes of memory, possibly leading to a local denial of service or
  privilege escalation. (CVE-2009-2848, Important)

  * Solar Designer reported a missing capability check in the z90crypt driver
  in the Linux kernel. This missing check could allow a local user with an
  effective user ID (euid) of 0 to bypass intended capability restrictions.
  (CVE-2009-1883, Moderate)

  * a flaw was found in the way the do_sigaltstack() function in the Linux
  kernel copies the stack_t structure to user-space. On 64-bit machines, this
  flaw could lead to a four-byte information leak. (CVE-2009-2847, Moderate)

  This update also fixes the following bugs:

  * the gcc flag '-fno-delete-null-pointer-checks' was added to the kernel
  build options. This prevents gcc from optimizing out NULL pointer checks
  after the first use of a pointer. NULL pointer bugs are often exploited by
  attackers. Keeping these checks is a safety measure. (BZ#517964)

  * the Emulex LPFC driver has been updated to version 8.0.16.47, which
  fixes a memory leak that caused memory allocation failures and system
  hangs. (BZ#513192)

  * an error in the MPT Fusion driver makefile caused CSMI ioctls to not
  work with Serial Attached SCSI devices. (BZ#516184)

  * this update adds the mmap_min_addr tunable and restriction checks to help
  prevent unprivileged users from creating new memory mappings below the
  minimum address. This can help prevent the exploitation of NULL pointer
  deference bugs. Note that mmap_min_addr is set to zero (disabled) by
  default for backwards compatibility. (BZ#517904)

  * time-outs resulted in I/O errors being logged to '/var/log/messages' when
  running 'mt erase' on tape drives using certain LSI MegaRAID SAS adapters,
  preventing the command from completing. The megaraid_sas driver's timeout
  value is now set to t ...
