linux vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.04
Summary:
The system could be made to crash or run programs as an administrator.
Software Description:
- linux: Linux kernel
Details:
Dmitry Vyukov discovered that the Linux kernel did not properly initialize
IPC object state in certain situations. A local attacker could use this to
escalate their privileges, expose confidential information, or cause a
denial of service (system crash).
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 15.04:
linux-image-3.19.0-30-generic 3.19.0-30.34
linux-image-3.19.0-30-generic-lpae 3.19.0-30.34
linux-image-3.19.0-30-lowlatency 3.19.0-30.34
linux-image-3.19.0-30-powerpc-e500mc 3.19.0-30.34
linux-image-3.19.0-30-powerpc-smp 3.19.0-30.34
linux-image-3.19.0-30-powerpc64-emb 3.19.0-30.34
linux-image-3.19.0-30-powerpc64-smp 3.19.0-30.34
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.
