SynopsisThe remote CentOS host is missing one or more security updates.
DescriptionUpdated kernel packages that fix security issues and bugs in the Red Hat Enterprise Linux 5 kernel are now available.
This update has been rated as having important security impact by the Red Hat Security Response Team.
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.
