Ubuntu Security Notice USN-2956-1
April 29, 2016

ubuntu-core-launcher vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 LTS

Summary:

ubuntu-core-launcher did not properly isolate snaps from one another.

Software Description:
- ubuntu-core-launcher: Snap application launcher

Details:

Zygmunt Krynicki discovered that ubuntu-core-launcher did not properly
sanitize its input and contained a logic error when determining the
mountpoint of bind mounts when using snaps on Ubuntu classic systems (eg,
traditional desktop and server). If a user were tricked into installing a
malicious snap with a crafted snap name, an attacker could perform a
delayed attack to steal data or execute code within the security context of
another snap. This issue did not affect Ubuntu Core systems.

Update instructions:

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

Ubuntu 16.04 LTS:
  ubuntu-core-launcher            1.0.27.1

In general, a standard system update will make all the necessary changes.
