Ytterligare information:

Marc Schoenefeld har upptäckt ett fel i hanteringen av indataströmpositioner när typsnittsrenderingsmotorn FreeType behandlar indata. Om en användare laddar en specialskriven typsnittsfil med en applikation som är länkad mot FreeType och dessa typsnittsglyfer sedan ritas med X FreeType library (libXft), kan en applikationskrasch orsakas. Möjligen kan även godtycklig kod exekveras.

Efter uppgradering behöver alla applikationer och tjänster som använder libfreetype6 startas om. I de flesta fall är det tillräckligt att logga ut och in igen. Skriptet checkrestart från paketet debian-goodies eller lsof kan hjälpa till med att hitta de processer som fortfarande använder den gamla versionen av libfreetype6.

För den stabila utgåvan (Lenny) har dessa problem rättats i version 2.3.7-2+lenny4.

Uttestningsutgåvan (Squeeze) och den instabila utgåvan (Sid) påverkas inte av detta problem.

Vi rekommenderar att ni uppgraderar era freetype-paket.
