Please Install the Updated Packages.

The kernel packages contain the Linux kernel, the core of any Linux operating system. These updated kernel packages fix the following security issues: A flaw was found in the virtual filesystem (VFS). A local unprivileged user could truncate directories to which they had write permission this could render the contents of the directory inaccessible. (CVE-2008-0001, Important) A flaw was found in the implementation of ptrace. A local unprivileged user could trigger this flaw and possibly cause a denial of service (system hang). (CVE-2007-5500, Important) A flaw was found in the way the Red Hat Enterprise Linux 4 kernel handled page faults when a CPU used the NUMA method for accessing memory on Itanium architectures. A local unprivileged user could trigger this flaw and cause a denial of service (system panic). (CVE-2007-4130, Important) A possible NULL pointer dereference was found in the chrp_show_cpuinfo function when using the PowerPC architecture. This may have allowed a local unprivileged user to cause a denial of service (crash). (CVE-2007-6694, Moderate) A flaw was found in the way core dump files were created. If a local user can get a root-owned process to dump a core file into a directory, which the user has write access to, they could gain read access to that core file. This could potentially grant unauthorized access to sensitive information. (CVE-2007-6206, Moderate) Two buffer overflow flaws were found in the Linux kernel ISDN subsystem. A local unprivileged user could use these flaws to cause a denial of service. (CVE-2007-6063, CVE-2007-6151, Moderate) As well, these updated packages fix the following bug: * when moving volumes that contain multiple segments, and a mirror segment is not the first in the mapping table, running the &quot pvmove /dev/[device] /dev/[device]&quot command caused a kernel panic. A &quot kernel: Unable to handle kernel paging request at virtual address [address]&quot error was logged by syslog. Red Hat Enterprise Linux 4 users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.
