Berørte pakker:

squid

Sårbar:

Referencer i sikkerhedsdatabaser:

I Debians fejlsporingssystem: Fejl 309504.
I Mitres CVE-ordbog: CVE-2005-1519.

Yderligere oplysninger:

Opstrømsudviklerne har fundet en fejl i DNS-opslagskoden i Squid, det populære program til mellemlagring af WWW-sider. Når DNS-klientens UDP-port (tildelt af styresystemet ved start) er ufiltreret og netværket ikke er beskyttet mod IP-forfalskning, kunne ondsindede brugere forfalske DNS-opslag, hvilket kunne medføre at brugerne blev omdirigeret til vilkårlige websteder.

I den gamle stabile distribution (woody) er dette problem rettet i version 2.4.6-2woody9.

I den stabile distribution (sarge) er dette problem allerede rettet i version 2.5.9-9.

I den ustabile distribution (sid) er dette problem allerede rettet i version 2.5.9-9.

Vi anbefaler at du opgraderer din squid-pakke.

Rettet i:

Debian GNU/Linux 3.0 (woody)
