freetype vulnerability

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

  • Ubuntu 7.04
  • Ubuntu 6.10
  • Ubuntu 6.06 LTS


Victor Stinner discovered that freetype did not correctly verify the
number of points in a TrueType font. If a user were tricked into using
a specially crafted font, a remote attacker could execute arbitrary code
with user privileges.
