Ytterligare information:

Imran Ghory upptäckte en kapplöpningseffekt i bzip2, en högkvalitativ blocksorterande filkomprimerare och -dekomprimerare. När en fil dekomprimerades i en katalog som angriparen har tillgång till kunde bunzip2 luras att sätta filbehörighet på en annan fil användaren har tillgång till.

För den stabila utgåvan (Woody) har detta problem rättats i version 1.0.2-1.woody2.

För uttestningsutgåvan (Sarge) har detta problem rättats i version 1.0.2-6.

För den instabila utgåvan (Sid) har detta problem rättats i version 1.0.2-6.

Vi rekommenderar att ni uppgraderar era bzip2-paket.
