Sårbar:

Referencer i sikkerhedsdatabaser:

I Mitres CVE-ordbog: CVE-2005-0094, CVE-2005-0095.

Yderligere oplysninger:

Flere sårbarheder er opdaget i Squid, cacheprogrammet til Internet-objekter, den populære WWW-proxycache. Projektet Common Vulnerabilities and Exposures har fundet frem til følgende sårbarheder:

CAN-2005-0094
"infamous41md" har opdaget et bufferoverløb i fortolkeren af Gopher-svar, hvilket kunne medføre hukommelsesødelæggelse og ville normalt få Squid til at gå ned.
CAN-2005-0095
"infamous41md" har opdaget et heltalsoverløb i modtageren af WCCP-meddelelser (Web Cache Communication Protocol). En angriber kunne sende et særligt fremstillet UDP-datagram, som fik Squid til at gå ned.

I den stabile distribution (woody) er disse problemer rettet i version 2.4.6-2woody5.

I den ustabile distribution (sid) er disse problemer rettet i version 2.5.7-4.

Vi anbefaler at du opgraderer din squid-pakke.

Rettet i:

Debian GNU/Linux 3.0 (woody)
