==========================================================================

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

- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

Applications using libgc could be made to crash or run programs as
your login.

Software Description:
- libgc: Boehm-Demers-Weiser garbage collecting storage allocator library

Details:

Kuang-che Wu discovered that multiple integer overflow vulnerabilities
existed in libgc. An attacker could use these to cause a denial of
service (application crash) or possibly execute arbitrary code.

Update instructions:

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

Ubuntu 16.10:

Ubuntu 16.04 LTS:

After a standard system update you need to restart applications using
