Please Install the Updated Packages.

The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: * A heap overflow flaw was found in the Linux kernel's Transparent Inter-Process Communication protocol (TIPC) implementation. A local, unprivileged user could use this flaw to escalate their privileges. (CVE-2010-3859, Important) * Missing sanity checks were found in gdth_ioctl_alloc() in the gdth driver in the Linux kernel. A local user with access to &quot /dev/gdth&quot on a 64-bit system could use these flaws to cause a denial of service or escalate their privileges. (CVE-2010-4157, Moderate) * A NULL pointer dereference flaw was found in the Bluetooth HCI UART driver in the Linux kernel. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2010-4242, Moderate) * A flaw was found in the Linux kernel's garbage collector for AF_UNIX sockets. A local, unprivileged user could use this flaw to trigger a denial of service (out-of-memory condition). (CVE-2010-4249, Moderate) * Missing initialization flaws were found in the Linux kernel. A local, unprivileged user could use these flaws to cause information leaks. (CVE-2010-3876, CVE-2010-4072, CVE-2010-4073, CVE-2010-4075, CVE-2010-4080, CVE-2010-4083, CVE-2010-4158, Low) Red Hat would like to thank Alan Cox for reporting CVE-2010-4242 Vegard Nossum for reporting CVE-2010-4249 Vasiliy Kulikov for reporting CVE-2010-3876 Kees Cook for reporting CVE-2010-4072 and Dan Rosenberg for reporting CVE-2010-4073, CVE-2010-4075, CVE-2010-4080, CVE-2010-4083, and CVE-2010-4158. This update also fixes the following bugs: * A flaw was found in the Linux kernel where, if used in conjunction with another flaw that can result in a kernel Oops, could possibly lead to privilege escalation. It does not affect Red Hat Enterprise Linux 4 as the sysctl panic_on_oops variable is turned on by default. However, as a preventive measure if the variable is turned off by an administrator, this update addresses the issue. Red Hat would like to thank Nelson Elhage for reporting this vulnerability. (BZ#659568) * On Intel I/O Controller Hub 9 (ICH9) hardware, jumbo frame support is achieved by using page-based sk_buff buffers without any packet split. The entire frame data is copied to the page(s) rather than some to the skb-&gt data area and some to the page(s) when performing a typical packet-split. T ...
