Detail
| A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 10.04 LTS Summary: Several security issues were fixed in the kernel. Software Description: - linux-ec2: Linux kernel for EC2 Details: A flaw was discovered in the Linux kernel's handling of SCTP handshake. A remote attacker could exploit this flaw to cause a denial of service (system crash). (CVE-2014-0101) An error was discovered in the Linux kernel's DCCP protocol support. A remote attacked could exploit this flaw to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2014-2523) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 10.04 LTS: After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.

| Title: | ELSA-2014:0475: kernel security and bug fix update (Important) | ||
| Description: | The kernel packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way the Linux kernel's netfilter connection tracking implementation for Datagram Congestion Control Protocol (DCCP) packets used the skb_header_pointer() function. A remote attacker could use this flaw to send a specially crafted DCCP packet to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-2523, Important) * A flaw was found in the way the Linux kernel's Adaptec RAID controller (aacraid) checked permissions of compat IOCTLs. A local attacker could use this flaw to bypass intended security restrictions. (CVE-2013-6383, Moderate) * A flaw was found in the way the handle_rx() function handled large network packets when mergeable buffers were disabled. A privileged guest user could use this flaw to crash the host or corrupt QEMU process memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process. (CVE-2014-0077, Moderate) The CVE-2014-0077 issue was discovered by Michael S. Tsirkin of Red Hat. This update also fixes several bugs. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section. All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect. | ||
