mime-support vulnerability
============================================================================

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

- Ubuntu 14.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

run-mailcap could be made to run programs as your login if it opened a
specially crafted file.

Software Description:
- mime-support: MIME support programs

Details:

Timothy D. Morgan discovered that the run-mailcap tool incorrectly filtered
certain shell metacharacters in filenames. If a user or automated system
were tricked into opening a file with a specially-crafted filename, a
remote attacker could possibly execute arbitrary code.

Update instructions:

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

Ubuntu 14.10:
  mime-support                    3.55ubuntu1.1

Ubuntu 14.04 LTS:
  mime-support                    3.54ubuntu1.1

Ubuntu 12.04 LTS:
  mime-support                    3.51-1ubuntu1.1

Ubuntu 10.04 LTS:
  mime-support                    3.48-1ubuntu1.1

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