Sårbar:

Referencer i sikkerhedsdatabaser:

I Mitres CVE-ordbog: CVE-2008-1612.

Yderligere oplysninger:

En svaghed er opdaget i squid, en cachende proxyserver. Fejlen blev introduceret opstrøms som reaktion på CVE-2007-6239, og annonceret af Debian i DSA-1482-1. Den involverer en overagressiv grænsekontrol på en størrelsesændring af et array, og kunne udnyttes af en autoriseret klient til at iværksætte en lammelsesangrebstilstand (denial of service) mod squid.

I den stabile distribution (etch), er disse problemer rettet i version 2.6.5-6etch2.

Vi anbefaler at du opgraderer dine squid-pakker.

Rettet i:

Debian GNU/Linux 4.0 (etch)
