========================================================================== Ubuntu Security Notice USN-2614-1 May 20, 2015
linux vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in the kernel.
Software Description: - linux: Linux kernel
Details:
Vincent Tondellier discovered an integer overflow in the Linux kernel's netfilter connection tracking accounting of loaded extensions. An attacker on the local area network (LAN) could potential exploit this flaw to cause a denial of service (system crash of targeted system). (CVE-2014-9715)
Jan Beulich discovered the Xen virtual machine subsystem of the Linux kernel did not properly restrict access to PCI command registers. A local guest user could exploit this flaw to cause a denial of service (host crash). (CVE-2015-2150)
A privilege escalation was discovered in the fork syscal vi the int80 entry on 64 bit kernels with 32 bit emulation support. An unprivileged local attacker could exploit this flaw to increase their privileges on the system. (CVE-2015-2830)
A memory corruption issue was discovered in AES decryption when using the Intel AES-NI accelerated code path. A remote attacker could exploit this flaw to cause a denial of service (system crash) or potentially escalate privileges on Intel base machines with AEC-GCM mode IPSec security association. (CVE-2015-3331)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 LTS: linux-image-3.13.0-53-generic 3.13.0-53.88 linux-image-3.13.0-53-generic-lpae 3.13.0-53.88 linux-image-3.13.0-53-lowlatency 3.13.0-53.88 linux-image-3.13.0-53-powerpc-e500 3.13.0-53.88 linux-image-3.13.0-53-powerpc-e500mc 3.13.0-53.88 linux-image-3.13.0-53-powerpc-smp 3.13.0-53.88 linux-image-3.13.0-53-powerpc64-emb 3.13.0-53.88 linux-image-3.13.0-53-powerpc64-smp 3.13.0-53.88
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.
