Ubuntu Security Notice USN-2977-1
May 16, 2016
linux-lts-vivid vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS
Summary:
The system could be made to crash or run programs as an administrator.
Software Description:
- linux-lts-vivid: Linux hardware enablement kernel from Vivid for Trusty
Details:
Philip Pettersson discovered that the Linux kernel's ASN.1 DER decoder did
not properly process certificate files with tags of indefinite length. A
local unprivileged attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code with administrative
privileges.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 14.04 LTS:
linux-image-3.19.0-59-generic 3.19.0-59.66~14.04.1
linux-image-3.19.0-59-generic-lpae 3.19.0-59.66~14.04.1
linux-image-3.19.0-59-lowlatency 3.19.0-59.66~14.04.1
linux-image-3.19.0-59-powerpc-e500mc 3.19.0-59.66~14.04.1
linux-image-3.19.0-59-powerpc-smp 3.19.0-59.66~14.04.1
linux-image-3.19.0-59-powerpc64-emb 3.19.0-59.66~14.04.1
linux-image-3.19.0-59-powerpc64-smp 3.19.0-59.66~14.04.1
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.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-vivid, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
