FreeType is a free, high-quality, portable font engine that can open and
manage font files. It also loads, hints, and renders individual glyphs
efficiently. These packages provide both the FreeType 1 and FreeType 2 font
A buffer overflow flaw was found in the way the FreeType library handled
malformed font files compressed using UNIX compress. If a user loaded a
specially-crafted compressed font file with an application linked against
FreeType, it could cause the application to crash or, possibly, execute
arbitrary code with the privileges of the user running the application.
Note: This issue only affects the FreeType 2 font engine.
Users are advised to upgrade to these updated packages, which contain a
backported patch to correct this issue. The X server must be restarted (log
out, then log back in) for this update to take effect.
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
