FreeType is a True Type Font rendering library.
Greg MacManus of iDefense Labs has discovered an integer overflow in the function bdfReadCharacters() when parsing BDF fonts.
A remote attacker could entice a user to use a specially crafted BDF font, possibly resulting in a heap-based buffer overflow and the remote execution of arbitrary code.
There is no known workaround at this time.
All FreeType users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/freetype-2.1.10-r3"
