Synopsis

A format string error has been discovered in Evolution, possibly
resulting in the execution of arbitrary code.

Background
=========
Evolution is a GNOME groupware application.

Affected packages

    -------------------------------------------------------------------
     Package                /   Vulnerable   /              Unaffected
    -------------------------------------------------------------------
  1  mail-client/evolution      < 2.12.3-r1               >= 2.12.3-r1

Description
==========
Ulf Harnhammar from Secunia Research discovered a format string error
in the emf_multipart_encrypted() function in the file mail/em-format.c
when reading certain data (e.g. the "Version:" field) from an encrypted
e-mail.

Impact
=====
A remote attacker could entice a user to open a specially crafted
encrypted e-mail, potentially resulting in the execution of arbitrary
code with the privileges of the user running Evolution.

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

Resolution
=========
All Evolution users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=mail-client/evolution-2.12.3-r1"
