========================================================================== Ubuntu Security Notice USN-2842-1 December 17, 2015
linux vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.04
Summary:
Several security issues were fixed in the kernel.
Software Description: - linux: Linux kernel
Details:
Jan Beulich discovered that the KVM svm hypervisor implementation in the Linux kernel did not properly catch Debug exceptions on AMD processors. An attacker in a guest virtual machine could use this to cause a denial of service (system crash) in the host OS. (CVE-2015-8104)
éæ°žå discovered that the ppp implementation in the Linux kernel did not ensure that certain slot numbers are valid. A local attacker with the privilege to call ioctl() on /dev/ppp could cause a denial of service (system crash). (CVE-2015-7799)
It was discovered that the virtual video osd test driver in the Linux kernel did not properly initialize data structures. A local attacker could use this to obtain sensitive information from the kernel. (CVE-2015-7884)
It was discovered that the driver for Digi Neo and ClassicBoard devices did not properly initialize data structures. A local attacker could use this to obtain sensitive information from the kernel. (CVE-2015-7885)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 15.04: linux-image-3.19.0-41-generic 3.19.0-41.46 linux-image-3.19.0-41-generic-lpae 3.19.0-41.46 linux-image-3.19.0-41-lowlatency 3.19.0-41.46 linux-image-3.19.0-41-powerpc-e500mc 3.19.0-41.46 linux-image-3.19.0-41-powerpc-smp 3.19.0-41.46 linux-image-3.19.0-41-powerpc64-emb 3.19.0-41.46 linux-image-3.19.0-41-powerpc64-smp 3.19.0-41.46
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.
