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:

A flaw was discovered in the user space memory copying for the pipe iovecs in the Linux kernel. An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or potentially escalate their privileges. (CVE-2015-1805)

A flaw was discovered in the kvm (kernel virtual machine) subsystem's kvm_apic_has_events function. A unprivileged local user could exploit this flaw to cause a denial of service (system crash). (CVE-2015-4692)

Daniel Borkmann reported a kernel crash in the Linux kernel's BPF filter JIT optimization. A local attacker could exploit this flaw to cause a denial of service (system crash). (CVE-2015-4700)

A flaw was discovered in how the Linux kernel handles invalid UDP checksums. A remote attacker could exploit this flaw to cause a denial of service using a flood of UDP packets with invalid checksums. (CVE-2015-5364)

A flaw was discovered in how the Linux kernel handles invalid UDP checksums. A remote attacker can cause a denial of service against applications that use epoll by injecting a single packet with an invalid checksum. (CVE-2015-5366)

Update instructions:

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

Ubuntu 14.04 LTS:
linux-image-3.13.0-58-generic 3.13.0-58.97
linux-image-3.13.0-58-generic-lpae 3.13.0-58.97
linux-image-3.13.0-58-lowlatency 3.13.0-58.97
linux-image-3.13.0-58-powerpc-e500 3.13.0-58.97
linux-image-3.13.0-58-powerpc-e500mc 3.13.0-58.97
linux-image-3.13.0-58-powerpc-smp 3.13.0-58.97
linux-image-3.13.0-58-powerpc64-emb 3.13.0-58.97
linux-image-3.13.0-58-powerpc64-smp 3.13.0-58.97

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.
