I Mitres CVE-ordbog: CVE-2004-0189.

Yderligere oplysninger:

En sårbarhed er opdaget i squid, et Internet-objektmellemlager (cache), hvorved adgangskontrollister baseret på URL'er kunne omgås (CAN-2004-0189). To andre fejl blev også rettet, med rettelserne squid-2.4.STABLE7-url_escape.patch (et bufferoverløb som ikke lader til at kunne udnyttes) og squid-2.4.STABLE7-url_port.patch (et potentielt lammelsesangreb).

I den stabile distribution (woody) er disse problemer rettet i version 2.4.6-2woody2.

I den ustabile distribution (sid) er disse problemer rettet i version 2.5.5-1.

Vi anbefaler at du opdaterer din squid-pakke.
