FreeType: User-assisted execution of arbitrary code

Background

FreeType is a True Type Font rendering library.

Description

Greg MacManus of iDefense Labs has discovered an integer overflow in the function bdfReadCharacters() when parsing BDF fonts.

Impact

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.

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-2.1.10-r3"
