A vulnerability has been discovered in FreeType allowing for the
execution of arbitrary code.

Background
=========
FreeType is a True Type Font rendering library.

Affected packages

    -------------------------------------------------------------------
     Package              /  Vulnerable  /                  Unaffected
    -------------------------------------------------------------------
  1  media-libs/freetype     < 2.3.4-r2                    >= 2.3.4-r2
                                                                 < 2.0

Description
==========
Victor Stinner discovered a heap-based buffer overflow in the function
Get_VMetrics() in src/truetype/ttgload.c when processing TTF files with
a negative n_points attribute.

Impact

A remote attacker could entice a user to open a specially crafted TTF
file, possibly resulting in the execution of arbitrary code with the
privileges of the user running FreeType.

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

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

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/freetype-2.3.4-r2"
