These new kernel packages fix the following security issues :

A flaw was found in the virtual filesystem (VFS). An unprivileged local 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 Xen PAL emulation on Intel 64 platforms. A guest Hardware-assisted virtual machine (HVM) could read the arbitrary physical memory of the host system, which could make information available to unauthorized users. (CVE-2007-6416, Important)

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, potentially containing sensitive information. (CVE-2007-6206, Moderate)

A buffer overflow flaw was found in the CIFS virtual file system. A remote,authenticated user could issue a request that could lead to a denial of service. (CVE-2007-5904, Moderate)

A flaw was found in the 'sysfs_readdir' function. A local user could create a race condition which would cause a denial of service (kernel oops). (CVE-2007-3104, Moderate)

As well, these updated packages fix the following bugs :

  - running the 'strace -f' command caused strace to hang,     without displaying information about child processes.

  - unmounting an unresponsive, interruptable NFS mount, for     example, one mounted with the 'intr' option, may have     caused a system crash.

  - a bug in the s2io.ko driver prevented VLAN devices from     being added. Attempting to add a device to a VLAN, for     example, running the 'vconfig add [device-name]     [vlan-id]' command caused vconfig to fail.

  - tux used an incorrect open flag bit. This caused     problems when building packages in a chroot environment,     such as mock, which is used by the koji build system.

Updated kernel packages that fix several security issues and several 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 kernel packages contain the Linux kernel, the core of any Linux operating system.
