DSA-741-1 bzip2 -- oändlig slinga

Rapporterat den:

2005-07-07

Berörda paket:

bzip2

Sårbara:

Referenser i säkerhetsdatabaser:

I Debians felrapporteringssystem: Fel 310803.
I Mitres CVE-förteckning: CVE-2005-1260.

Ytterligare information:

Chris Evans upptäckte att ett specialskrivet arkiv kunde orsaka en oändlig slinga i bzip2, en högkvalitativ blocksorterande filkomprimerare. Under uppackning leder detta till att utdatafilen växer i oändlighet och till slut fyller upp hela disken. På system som automatiskt packar upp bzip2-arkiv kan detta leda till en överbelastning.

För den gamla stabila distributionen (Woody) har detta problem rättats i version 1.0.2-1.woody5.

För den stabila utgåvan (Sarge) har detta problem rättats i version 1.0.2-7.

För den instabila utgåvan (Sid) har detta problem rättats i version 1.0.2-7.

Vi rekommenderar att ni uppgraderar ert bzip2-paket.
