DSA-2112-1 bzip2 -- heltalsoverløb

Rapporteret den:

20. sep 2010

Berørte pakker:

bzip2

Sårbar:

Referencer i sikkerhedsdatabaser:

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

Yderligere oplysninger:

Mikolaj Izdebski opdagede en heltalsoverløbsfejl i funktionen BZ2_decompress i bzip2/libbz2. En angriber kunne anvende en fabrikeret bz2-fil til at forårsage et lammelsesangreb (applikationsnedbrud) eller potentielt udføre vilkårlig kode. (CVE-2010-0405)

Efter en opgradering, skal alle services, som anvender libbz2, genstartes.

Denne opdatering indeholder også genopbyggede dpkg-pakker, som er statisk linkede til den rettede udgave af libbz2. Opdaterede pakker til clamav, som også er påvirket af problemet, vil blive stillet til rådighed via debian-volatile.

I den stabile distribution (lenny), er dette problem rettet i version 1.0.5-1+lenny1.

I distributionen testing (squeeze) og i den ustabile distribution (sid), vil dette problem i bzip2 snart blive rettet. Opdaterede dpkg-pakker er ikke nødvendige i testing/unstable.

Vi anbefaler at du opgraderer dine bzip2- / dpkg-pakker.
