DSA-1991-1 squid/squid3 -- lammelsesangreb

Rapporteret den:

4. feb 2010

Berørte pakker:

squid/squid3

Sårbar:

Referencer i sikkerhedsdatabaser:

I Debians fejlsporingssystem: Fejl 534982.
I Mitres CVE-ordbog: CVE-2009-2855, CVE-2010-0308.

Yderligere oplysninger:

To lammelsesangrebssårbarheder (denial of service) er opdaget i squid og squid3, en webproxy. Projektet Common Vulnerabilities and Exposures har registreret følgende problemer:

CVE-2009-2855
Bastian Blank opdagede, at det var muligt at forårsage et lammelsesangreb gennem en fabrikeret auth-header med visse kommaadskillelser.
CVE-2010-0308
Tomas Hoger opdagede, at det var muligt at forårsage et lammelsesangreb gennem ugyldige DNS-pakker kun indeholdende en header.

I den stabile distribution (lenny), er disse problemer rettet i version 2.7.STABLE3-4.1lenny1 af squid-pakken og i version 3.0.STABLE8-3+lenny3 af squid3-pakken.

I den gamle stabile distribution (etch), er disse problemer rettet i version 2.6.5-6etch5 af squid-pakken og i version 3.0.PRE5-5+etch2 af squid3-pakken.

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

Vi anbefaler at du opgraderer dine squid/squid3-pakker.
