  operating system.

  * the Xen implementation did not prevent applications running in a
  para-virtualized guest from modifying CR4 TSC. This could cause a local
  denial of service. (CVE-2007-5907, Important)
  
  * Tavis Ormandy reported missing boundary checks in the Virtual Dynamic
  Shared Objects (vDSO) implementation. This could allow a local unprivileged
  user to cause a denial of service or escalate privileges. (CVE-2008-3527,
  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, CVE-2008-3833,
  Important)
  
  * a flaw was found in the Linux kernel splice implementation. This could
  cause a local denial of service when there is a certain failure in the
  add_to_page_cache_lru() function. (CVE-2008-4302, Important)
  
  * a flaw was found in the Linux kernel when running on AMD64 systems.
  During a context switch, EFLAGS were being neither saved nor restored. This
  could allow a local unprivileged user to cause a denial of service.
  (CVE-2006-5755, Low)
  
  * a flaw was found in the Linux kernel virtual memory implementation. This
  could allow a local unprivileged user to cause a denial of service.
  (CVE-2008-2372, Low)
  
  * an integer overflow was discovered in the Linux kernel Datagram
  Congestion Control Protocol (DCCP) implementation. This could allow a
  remote attacker to cause a denial of service. By default, remote DCCP is
  blocked by SELinux. (CVE-2008-3276, Low)
  
  In addition, these updated packages fix the following bugs:
  
  * random32() seeding has been improved. 
  
  * in a multi-core environment, a race between the QP async event-handler
  and the destro_qp() function could occur. This led to unpredictable results
  during invalid memory access, which could lead to a kernel crash.
  
  * a format string was omitted in the call to the request_module() function.
  
  * a stack overflow caused by an infinite recursion bug in the binfmt_misc
  kernel module was corrected.
  
  * the ata_scsi_rbuf_get() and ata_scsi_rbuf_put() functions now check for
  scatterlist usage before calling kmap_atomic().
  
  * a sentinel NUL byte was added to the device_write() function to ensure
  that lspace.name is NUL-terminated.
  
  * in the character device driver, a range_is_allowed() check was added to
  the read_mem() and write_mem() functions. It was possible for an
  illegitimate application to b ...
