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 NULL pointer dereference flaw was found in the sctp_rcv_ootb() function in the Linux kernel Stream Control Transmission Protocol (SCTP) implementation. A remote attacker could send a specially-crafted SCTP packet to a target system, resulting in a denial of service. (CVE-2010-0008, Important) * a NULL pointer dereference flaw was found in the Linux kernel. During a core dump, the kernel did not check if the Virtual Dynamically-linked Shared Object page was accessible. On Intel 64 and AMD64 systems, a local, unprivileged user could use this flaw to cause a kernel panic by running a crafted 32-bit application. (CVE-2009-4271, Important) * an information leak was found in the print_fatal_signal() implementation in the Linux kernel. When &quot /proc/sys/kernel/print-fatal-signals&quot is set to 1 (the default value is 0), memory that is reachable by the kernel could be leaked to user-space. This issue could also result in a system crash. Note that this flaw only affected the i386 architecture. (CVE-2010-0003, Moderate) * on AMD64 systems, it was discovered that the kernel did not ensure the ELF interpreter was available before making a call to the SET_PERSONALITY macro. A local attacker could use this flaw to cause a denial of service by running a 32-bit application that attempts to execute a 64-bit application. (CVE-2010-0307, Moderate) * missing capability checks were found in the ebtables implementation, used for creating an Ethernet bridge firewall. This could allow a local, unprivileged user to bypass intended capability restrictions and modify ebtables rules. (CVE-2010-0007, Low) This update also fixes the following bugs: * under some circumstances, a locking bug could have caused an online ext3 file system resize to deadlock, which may have, in turn, caused the file system or the entire system to become unresponsive. In either case, a reboot was required after the deadlock. With this update, using resize2fs to perform an online resize of an ext3 file system works as expected. (BZ#553135) * some ATA and SCSI devices were not honoring the barrier=1 mount option, which could result in data loss after a crash or power loss. This update applies a patch to the Linux SCSI driver to ensure ordered write caching. This solution does not provide cache flus ...
