libwmf vulnerabilities
==========================================================================

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

- Ubuntu 15.04
- Ubuntu 14.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

libwmf could be made to crash or run programs as your login if it opened a
specially crafted file.

Software Description:
- libwmf: Windows metafile conversion tools

Details:

Fernando Muñoz and Stefan Cornelius discovered that libwmf incorrectly
handled certain malformed images. If a user or automated system were
tricked into opening a crafted image file, an attacker could cause a denial
of service or execute arbitrary code with privileges of the user invoking
the program.

Update instructions:

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

Ubuntu 15.04:
  libwmf0.2-7                     0.2.8.4-10.3ubuntu1.15.04.1

Ubuntu 14.10:
  libwmf0.2-7                     0.2.8.4-10.3ubuntu1.14.10.1

Ubuntu 14.04 LTS:
  libwmf0.2-7                     0.2.8.4-10.3ubuntu1.14.04.1

Ubuntu 12.04 LTS:
  libwmf0.2-7                     0.2.8.4-10ubuntu1.1

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