(RHSA-2007:0169) Important: kernel security and bug fix update

The Linux kernel handles the basic functions of the operating system.

These new kernel packages contain fixes for the following security issues:

• a flaw in the IPv6 socket option handling that allowed a local user to
  read arbitrary kernel memory (CVE-2007-1000, Important).

• a flaw in the IPv6 socket option handling that allowed a local user to
  cause a denial of service (CVE-2007-1388, Important).

• a flaw in the utrace support that allowed a local user to cause a denial
  of service (CVE-2007-0771, Important).

In addition to the security issues described above, a fix for a memory leak
in the audit subsystem and a fix for a data corruption bug on s390 systems
have been included.

Red Hat Enterprise Linux 5 users are advised to upgrade to these erratum
packages, which are not vulnerable to these issues.
