DSA-741-1 bzip2 -- uendelig løkke

Rapporteret den:

7. jul 2005

Berørte pakker:

bzip2

Sårbar:

Referencer i sikkerhedsdatabaser:

I Debians fejlsporingssystem: Fejl 310803.
I Mitres CVE-ordbog: CVE-2005-1260.

Yderligere oplysninger:

Chris Evans har opdaget at er særligt fremstillet arkiv kunne udløse en uendelig løkke i bzip2, et bloksorterende filkomprimeringsprogram af høj kvalitet. Under udpakningen af arkivet medførte det en uddatafil der blev ved med at vokse indtil disken var fyldt op. På systemer der automatisk udpakker bzip2-arkiver, kunne det ende med et lammelsesangreb (DoS, Denial of Service).

I den gamle stabile distribution (woody) er dette problem rettet i version 1.0.2-1.woody5.

I den stabile distribution (sarge) er dette problem rettet i version 1.0.2-7.

I den ustabile distribution (sid) er dette problem rettet i version 1.0.2-7.

Vi anbefaler at du opgraderer din bzip2-pakke.

Rettet i:

Debian GNU/Linux 3.0 (woody)
