Flere heltalsunderløb er opdaget, hvilket kunne gøre det muligt for fjernangribere at forårsage et lammelsesangreb (denial of service).
CVE-2006-1861
Chris Evans har opdaget flere heltalsoverløb, der kunne føre til et lammelsesangreb eller muligvis endda føre til udførelse af vilkårlig kode.
CVE-2006-2493
Flere andre heltalsoverløb er opdaget, hvilket måske kunne føre til udførelse af vilkårlige kode.
CVE-2006-2661
En null-pointerdereference kunne forårsage et lammelsesangreb.

I den gamle stabile distribution (woody) er disse problemer rettet i version 2.0.9-1woody1.

I den stabile distribution (sarge) er disse problemer rettet i version 2.1.7-2.5.

I den ustabile distribution (sid) vil disse problemer snart blive rettet

Vi anbefaler at du opgraderer dine libfreetype-pakker.
