DSA-1987-1 lighttpd -- lammelsesangreb

Rapporteret den:

2. feb 2010

Berørte pakker:

lighttpd

Sårbar:

Referencer i sikkerhedsdatabaser:

I Mitres CVE-ordbog: CVE-2010-0295.

Yderligere oplysninger:

Li Ming opdagede at lighttpd, en lille og hurtig webserver med minimalt hukommelsesforbrug, er sårbar over for et lammelsesangreb (denial of service) på grund af dårlig hukommelseshåndtering. Ved langsomt at sende meget små dele af forespørgselsdata, får lighttpd til at allokere nye buffere for hver læsning, i stedet for at udvide de eksisterende. En angriber kunne misbruge dette til at forårsage en lammelsesangrebstilstand på grund af forbrug af al hukommelsen.

I den gamle stabile distribution (etch), er dette problem rettet i version 1.4.13-4etch12.

I den stabile distribution (lenny), er dette problem rettet i version 1.4.19-5+lenny1.

I distributionen testing (squeeze) og i den ustabile (sid) distribution, vil dette problem snart blive rettet.

Vi anbefaler at du opgraderer dine lighttpd-pakker.
