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

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
