Synopsis
=======
Format string vulnerabilities in Dia may lead to the execution of
arbitrary code.

Background
=========
Dia is a GTK+ based diagram creation program.

Affected packages
================
    -------------------------------------------------------------------
     Package         /  Vulnerable  /                       Unaffected
    -------------------------------------------------------------------
  1  app-office/dia      < 0.95.1                            >= 0.95.1

Description
==========
KaDaL-X discovered a format string error within the handling of
filenames. Hans de Goede also discovered several other format string
errors in the processing of dia files.

Impact
=====
By enticing a user to open a specially crafted file, a remote attacker
could exploit these vulnerabilities to execute arbitrary code with the
rights of the user running the application.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All Dia users should upgrade to the latest available version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-office/dia-0.95.1"
