Referenser i säkerhetsdatabaser:

I Mitres CVE-förteckning: CVE-2010-0405.

Ytterligare information:

Mikolaj Izdebski har upptäckt ett heltalsspill i funktionen BZ2_decompress i bzip2/libbz2. En angripare kunde använda en specialskriven bz2-fil för att orsaka en överbelastning (applikationskrasch) eller möjligen exekvera godtycklig kod. (CVE-2010-0405)

Efter uppgraderingen behöver alla tjänster som använder libbz2 startas om.

Denna uppdatering tillhandahåller också ombyggda dpkg-paket, som är statiskt länkade till den rättade versionen av libbz2. Uppdaterade paket för clamav, som också påverkas av detta problem, kommer tillhandahållas i debian-volatile.

För den stabila utgåvan (Lenny) har detta problem rättats i version 1.0.5-1+lenny1.

För uttestningsutgåvan (Squeeze) och den instabila utgåvan (Sid) kommer detta problem i bzip2 att rättas inom kort. Uppdaterade dpkg-paket behövs inte för dessa utgåvor.

Vi rekommenderar att ni uppgraderar era bzip2 / dpkg-paket.
