Detail

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:

Sun Baoliang discovered a use after free flaw in the Linux kernel's SCTP (Stream Control Transmission Protocol) subsystem during INIT collisions. A remote attacker could exploit this flaw to cause a denial of service (system crash) or potentially escalate their privileges on the system. (CVE-2015-1421)

Marcelo Leitner discovered a flaw in the Linux kernel's routing of packets to too many different dsts/too fast. A remote attacker can exploit this flaw to cause a denial of service (system crash). (CVE-2015-1465)

An integer overflow was discovered in the stack randomization feature of the Linux kernel on 64 bit platforms. A local attacker could exploit this flaw to bypass the Address Space Layout Randomization (ASLR) mitigation mechanism. (CVE-2015-1593)

An information leak was discovered in the Linux kernel's handling of userspace configuration of the link layer control (LLC). A local user could exploit this flaw to read data from other sysctl settings. (CVE-2015-2041)

An information leak was discovered in how the Linux kernel handles setting the Reliable Datagram Sockets (RDS) settings. A local user could exploit this flaw to read data from other sysctl settings. (CVE-2015-2042)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.04 LTS:
linux-image-3.13.0-49-generic 3.13.0-49.81
linux-image-3.13.0-49-generic-lpae 3.13.0-49.81
linux-image-3.13.0-49-lowlatency 3.13.0-49.81
linux-image-3.13.0-49-powerpc-e500 3.13.0-49.81
linux-image-3.13.0-49-powerpc-e500mc 3.13.0-49.81
linux-image-3.13.0-49-powerpc-smp 3.13.0-49.81
linux-image-3.13.0-49-powerpc64-emb 3.13.0-49.81
linux-image-3.13.0-49-powerpc64-smp 3.13.0-49.81

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.
