tag_insight = "The kernel packages contain the Linux kernel, the core of any Linux
  operating system.

  These updated packages fix the following security issues:
  
  * the absence of a protection mechanism when attempting to access a
  critical section of code has been found in the Linux kernel open file
  descriptors control mechanism, fcntl. This could allow a local unprivileged
  user to simultaneously execute code, which would otherwise be protected
  against parallel execution. As well, a race condition when handling locks
  in the Linux kernel fcntl functionality, may have allowed a process
  belonging to a local unprivileged user to gain re-ordered access to the
  descriptor table. (CVE-2008-1669, Important)
  
  * a possible hypervisor panic was found in the Linux kernel. A privileged
  user of a fully virtualized guest could initiate a stress-test File
  Transfer Protocol (FTP) transfer between the guest and the hypervisor,
  possibly leading to hypervisor panic. (CVE-2008-1619, Important)
  
  * the absence of a protection mechanism when attempting to access a
  critical section of code, as well as a race condition, have been found
  in the Linux kernel file system event notifier, dnotify. This could allow a
  local unprivileged user to get inconsistent data, or to send arbitrary
  signals to arbitrary system processes. (CVE-2008-1375, Important)
  
  Red Hat would like to thank Nick Piggin for responsibly disclosing the
  following issue:
  
  * when accessing kernel memory locations, certain Linux kernel drivers
  registering a fault handler did not perform required range checks. A local
  unprivileged user could use this flaw to gain read or write access to
  arbitrary kernel memory, or possibly cause a kernel crash.
  (CVE-2008-0007, Important)
  
  * the absence of sanity-checks was found in the hypervisor block backend
  driver, when running 32-bit paravirtualized guests on a 64-bit host. The
  number of blocks to be processed per one request from guest to host, or
  vice-versa, was not checked for its maximum value, which could have allowed
  a local privileged user of the guest operating system to cause a denial of
  service. (CVE-2007-5498, 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 bugs:
  
  * on IBM System z architectures, when running QIOASSIST enabled QDIO
  devices in an IBM z/VM environment, the output qu ...
