Yderligere oplysninger:

Marc Schoenefeld fandt en positioneringsfejl i en inddatastream, i den måde skrifttyperenderingmaskinen FreeType behandlede inddatafilstreams. Hvis en bruger indlæste en særligt fremstillet skrifttypefil med en applikation linket mod FreeType, og relevante skripttypeglyffer efterfølgende blev renderet med X's FreeType-bibliotek (libXft), kunne det forårsage at applikationen gik ned eller muligvis udførelse af vilkårlig kode.

Efter opgraderingen, bør man genstarte alle kørende programmer og tjenester, som anvender libfreetype6. I de fleste tilfælde er det tilstrækkeligt at logge ud og ind igen. Skriptet checkrestart fra pakken debian-goodies eller lsof kan hjælpe med at finde ud af hvilke processer, der stadig anvender den gamle version af libfreetype6.

I den stabile distribution (lenny), er disse problemer rettet i version 2.3.7-2+lenny4.

Distributionen testing (squeeze) og den ustabile distribution (sid) er ikke påvirket af dette problem.

Vi anbefaler at du opgraderer dine freetype-pakker.

Rettet i:

Debian GNU/Linux 5.0 (lenny)
