This kernel update fixes quite a number of security problems :

  - A remote attacker could crash the IPSec/IPv6 stack by     sending a bad ESP packet. This requires the host to be     able to receive such packets (default filtered by the     firewall). (CVE-2007-6282)

  - A problem in SIT IPv6 tunnel handling could be used by     remote attackers to immediately crash the machine.
    (CVE-2008-2136)

  - On x86_64 a denial of service attack could be used by     local attackers to immediately panic / crash the     machine. (CVE-2008-1615)

  - An information leakage during coredumping of root     processes was fixed. (CVE-2007-6206)

  - Fixed a SMP ordering problem in fcntl_setlk could     potentially allow local attackers to execute code by     timing file locking. (CVE-2008-1669)

  - Fixed a dnotify race condition, which could be used by     local attackers to potentially execute code.
    (CVE-2008-1375)

  - A ptrace bug could be used by local attackers to hang     their own processes indefinitely. (CVE-2007-5500)

  - Clear the 'direction' flag before calling signal     handlers. For specific not yet identified programs under     specific timing conditions this could potentially have     caused memory corruption or code execution.
    (CVE-2008-1367)

  - The isdn_ioctl function in isdn_common.c allowed local     users to cause a denial of service via a crafted ioctl     struct in which ioctls is not null terminated, which     triggers a buffer overflow. (CVE-2007-6151)

Non security related changes :

OCFS2 was updated to version v1.2.9-1-r3100.

Also a huge number of bugs were fixed. Please refer to the RPM changelog for a detailed list.

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.

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.

Red Hat Enterprise Linux 5 users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.

The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2008-150:05 advisory.

    The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system.  The     kernel handles the basic functions of the operating system:  memory allocation, process allocation, device     input and output, etc.
